Chapter 11, Problem 85QAP

Interpretation Introduction

Interpretation: The percentage increase in the rate constant needs to be calculated, if the activation energy for the reaction is 85 kJ.

Concept introduction: The activation energy is denoted by symbol E_a, it is the minimum amount of energy that must be possessed by the molecules so that formation of products can take place. The slope of the Arrhenius plot can be used to find the activation energy for a given reaction. The Arrhenius equation can be written as follows:

  $\text{ln k=}\frac{{\text{-E}}_{\text{a}}}{\text{RT}}\text{+lnA}$

Here, k is rate constant, R is Universal gas constant, T is temperature and A is Arrhenius constant.
