Chapter 11.7, Problem 11.12E

(a)

Interpretation Introduction

Interpretation:

The overall reaction equation of the given below reaction has to be written.

  $\begin{array}{l}ICl\left(g\right)+H_2\left(g\right)\rightleftharpoons HI\left(g\right)+HCl\left(g\right)fast\\ \\ HI\left(g\right)+ICl\left(g\right)\to HCl\left(g\right)+I_2\left(g\right)slow\end{array}$

(b)

Interpretation Introduction

Interpretation:

The rate law predicted by the given below mechanism has to be derived.

  $\begin{array}{l}ICl\left(g\right)+H_2\left(g\right)\rightleftharpoons HI\left(g\right)+HCl\left(g\right)fast\\ \\ HI\left(g\right)+ICl\left(g\right)\to HCl\left(g\right)+I_2\left(g\right)slow\end{array}$

(c)

Interpretation Introduction

Interpretation:

The dependency of rate law on the concentration of one of the products of the reaction has to be checked.

(d)

Interpretation Introduction

Interpretation:

An explanation has to be given whether the rate constant determined from the initial rate of the reaction equal the rate constant determined at a time when $80\%$ of the reactants had been consumed.
