Is it true that the effect of a catalyst on a chemical reaction is to react with product, effectively removing it and shifting the equilibrium to the right?

Answers

Answer 1

No, it is not true that the effect of a catalyst on a chemical reaction is to react with product, effectively removing it and shifting the equilibrium to the right.

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. It achieves this by providing an alternative reaction pathway with a lower activation energy. The catalyst itself is not consumed in the reaction and is therefore not considered a reactant or a product.

A catalyst does not shift the equilibrium of a chemical reaction, but it can help the reaction reach equilibrium more quickly. Once the reaction reaches equilibrium, the catalyst can speed up the rate of the forward and reverse reactions equally, keeping the concentrations of reactants and products constant.

In summary, the function of a catalyst is to increase the rate of a chemical reaction without being consumed itself and does not affect the position of equilibrium.

What type of compound is KBr?

Answers

KBr is an ionic compound . It is made up of an ionic link between a metal (potassium, K) and a nonmetal (bromine, Br).

As the bromine atom in KBr receives an electron to become a negatively charged ion, the potassium atom loses an electron to become a positively charged ion (K+) (Br-). The ionic bond in KBr is produced by the resultant attraction between the positive and negative ions.

An ionic compound is a chemical compound composed of positively charged ions (cations) and negatively charged ions (anions) that are held together by electrostatic forces of attraction. These compounds are formed when one or more electrons are transferred from a metal atom to a nonmetal atom, resulting in the formation of ions with opposite charges.

Ionic compounds typically have high melting and boiling points, are brittle, and are good conductors of electricity in the molten or aqueous state.

Constants Four electrons are located at the corners of a square 10.0 nm on a side, with an alpha particle at its midpoint. Consider the alpha particle as your system.

Answers

The work is needed to move the alpha particle to the midpoint of one of the sides of the square is - 7* 10⁻²² J

At the intersection of a square, four electrons are placed. Therefore, we will start by determining the electrostatic potential at the square's center.

So, it is shown here as

V = 4 kQ/r

Where.

r= distance of corner of the square from it center

r = a/√2

r = 10 nm/ √2 = 7.07 nm

Q= e = -1.6 x 10⁻¹⁹ C

The net potential is given by;

V = 4 x 9 x10⁹ x (-1.6 x 10⁻⁹)

              7.07 x 10⁻⁹

V= 0.815 V

at this time, the alpha particle's potential energy

Ui = qV

Ui = 2 x 1.6 x  10⁻¹⁹ x - 0.815 = -2.6 x 10⁻¹⁹J

Then, one of the sides' midpoints Provided that's the electrostatic potential as

V = 2 kQ + 2 kQ

         r₁         r₂

So,

r₁ = a/2 = 5nm

r₂ = √(a/2)²+a² = √5 a /2

r₂ = 11.2 nm

now potential is given as

V = 2 9x 10⁹ * (-1.6 x 10⁻¹⁹) + 2 9x 10⁹ * (-1.6 x 10⁻¹⁹)

                    5x 10⁻⁹                        11.2 x 10⁻⁹

V = - 0.576 - 0.257 = - 0.833V

Final potential energy is now presented as

Uf = q * V = 2 * 1.6 * 10⁻¹⁹ -0.833 = -2.67 x 10⁻¹⁹ J

Now work done in this process is given as

W = Uf - Ui

W = (- 0.267 * 10⁻¹⁹) - (-0.26 * 10⁻¹⁹)

W = - 7* 10⁻²² J

A solution is prepared by dissolving 17. 75 g sulfuric acid, h2so4, in enough water to make exactly 100. 0 ml of solution. If the density of the solution is 1. 1094 g/ml, what is the weight % h2so4 in the solution?.

Answers

The weight percent of H₂SO4in the solution is 15.98%.

To calculate the weight percent of H₂SO4in the solution, we need to first find the mass of H₂SO4in the solution. We can use the molarity of the solution and the molar mass of H₂SO4to calculate the mass of H₂SO4present:

Calculate the number of moles of 4:

Molar mass of H₂SO4 = 2(1.008 + 32.06 + 4(16.00)) = 98.08 g/mol

Number of moles of H₂SO4= mass of H₂SO4 / molar mass of H₂SO4

= 17.75 g / 98.08 g/mol

= 0.1809 mol

Calculate the mass of the solution:

Mass of the solution = volume of the solution x density of the solution

= 100.0 ml x 1.1094 g/ml

= 110.94 g

Calculate the mass of H₂SO4in the solution:

Mass of H₂SO4in solution = number of moles of H₂SO4x molar mass of H₂SO4

= 0.1809 mol x 98.08 g/mol

= 17.73 g

Now that we know the mass of H₂SO4in the solution, we can calculate the weight percent of H₂SO4:

Weight % H₂SO4= (mass of H₂SO4/ mass of solution) x 100%

= (17.73 g / 110.94 g) x 100%

= 15.98%

Therefore, the weight percent of H₂SO4in the solution is 15.98%.

Answers

Na+ would enter the cell while K+ would exit. In the postsynaptic or postjunctional membrane, ACh diffuses and binds to certain receptors.

What happens in the postsynaptic cell when acetylcholine binds to the receptor?

In the postsynaptic or postjunctional membrane, ACh diffuses across the synaptic cleft and binds to specific receptors. An altered conformation of a membrane channel that is selectively permeable to both Na+ and K+ results from the binding of ACh to its receptors.

When ACh binds to its receptors, it modifies the structure of a membrane circuit that is selectively permeable to both Na+ and K+. When cholinergic receptors on skeletal muscle fibres interact with each other, ligand-gated sodium channels inside the cell membrane are opened.

The muscle fibre is then exposed to sodium ions, which causes the muscle to contract. By stimulating nonpostsynaptic AChRs, ACh specifically inhibits presynaptic nerve terminal specialisation and postnatal AChR cluster (synaptic differentiation), and by inhibiting postsynaptic AChRs, it inhibits motor short tapered bandwidth or engine axon splitting (synaptic growth).

Ion channels in the muscle fibre membrane are opened by the neurotransmitter acetylcholine (ACh) attaching to postsynaptic receptors.

According to the Gibbs free energy equation (ΔG = ΔH - TΔS), the spontaneity of a reaction is determined by the sign and magnitude of the enthalpy change (ΔH) and the entropy change (ΔS).

If ΔH is negative (exothermic) and ΔS is positive (increase in disorder), the reaction will be spontaneous at all temperatures. This indicates that the products are more energetically stable than the reactants.

If ΔH is positive (endothermic) and ΔS is negative (decrease in disorder), the reaction will be non-spontaneous at all temperatures. This indicates that the products are less energetically stable than the reactants.

If ΔH is positive and ΔS is positive, the reaction will be spontaneous only at high temperatures. This indicates that the products are less energetically stable than the reactants, but the increase in entropy at high temperatures can drive the reaction forward.

If ΔH is negative and ΔS is negative, the reaction will be spontaneous only at low temperatures. This indicates that the products are more energetically stable than the reactants, but the decrease in entropy at low temperatures can drive the reaction forward.
