Chapter 11, Problem 88QAP

Interpretation Introduction

Interpretation:

The two-point equation which relates with k and activation energy for a catalysed and an uncatalaysed reaction at same temperature should be derived.

Concept introduction:

The substance which increases the rate of reaction without consuming overall during the reaction is known as catalyst. It decreases the activation energy of the reaction so reaction will complete on less time. The activation energy is the minimum amount of energy that is needed to change the reactant molecule to product molecules. The relation between activation energy, rate constant and temperature can be written as:

${\text{k = A e}}^{\text{-Ea/RT}}$

Here:

• k= rate constant
• A = Frequency constant
• R = gas constant
• T = Temperature
