Chapter 6, Problem 6.12P

(a)

Interpretation Introduction

Interpretation:

The fraction of collisions that have sufficient energy for given reaction at temperature ${\text{20}}^{\text{o}}\text{C}$ has to be calculated.

Concept Introduction:

Based on Boltzmann distribution the fractions of collisions that has least kinetic energy ${\text{E}}_{\text{a}}$ is calculated.

$\begin{array}{l}f=e^{\raisebox{1ex}{$-Ea$}\!\left/ \!\raisebox{-1ex}{$RT$}\right.}\\ \boxed{\begin{array}{c}here,f=fraction\\ E_a=activationenergy\\ R=g\text{as}\text{constant}\\ \text{T=}\text{temperature}\end{array}}\end{array}$

Interpretation Introduction

Interpretation:

The fraction of collisions that have sufficient energy for given reaction at temperature ${\text{200}}^{\text{o}}\text{C}$ has to be calculated.

Concept Introduction:

Based on Boltzmann distribution the fractions of collisions that has least kinetic energy ${\text{E}}_{\text{a}}$ is calculated.
