Chapter 5.13, Problem 38P

Interpretation Introduction

Interpretation:

The parameter which is different for a reaction carried out in the presence of a catalyst compared with the same reaction carried out in the absence of a catalyst should be determined from the given parameters.

Concept introduction:

The process of acceleration or retardation of the rate of a chemical reaction brought about by the addition of a substance to the reaction medium is called catalysis.  And the substance used for this process is known as catalyst and which is not consumed in the reaction.

A catalyst will change the energy difference between the reactants and the transition state, but it will not change the energy difference between the reactant and the products.
