Chapter 7, Problem 7D.2E

Interpretation Introduction

Interpretation:

The value of $E_{\text{a}}$ (activation energy) for the reaction, $2\text{HI}\left(\text{g}\right)\to {\text{H}}_2\left(\text{g}\right)+{\text{I}}_2\left(\text{g}\right)$ has to be calculated.

Concept Introduction:

The activation energy is the minimum energy (over threshold energy) required by the reactant molecules to convert into products. An important condition for reaction to proceed is that the reacting species must be able to pass potential energy barrier. This is done by making use of activation energy $\left(E_{\text{a}}\right)$.
