Question

The addition of a catalyst in a chemical reaction

(A) increases the concentration of products at equilibrium.

(B) increases the fraction of reactant molecules with a given kinetic energy.

(C) provides an alternate path with a different activation energy.

(D) lowers the enthalpy change in the overall reaction

Could you explain which option you chose? And why

Answer 1

(C) provides an alternate path with a different activation energy

The reason for this choice is because this is known to be the mechanism by which catalysts do what they do. They increase the rate of the reaction by providing an alternate path which has a lower activation energy.
