Chapter 12, Problem 12.138MP

(a)

Interpretation Introduction

Interpretation:

The initial rate of production of ${\text{I}}_{\text{2}}$ in molecules per min has to be calculated.

Concept Introduction:

Rate of reaction:

The rate of a reaction is defined by the change in concentration of substrate (reactant) or target (product) with change in time.

$\text{Rate}\text{=}\frac{\text{Concentration}\text{change}\left(\text{in}\text{reactant}\text{or}\text{product}\right)}{\text{Time}\text{change}}$

(b)

Interpretation Introduction

Interpretation:

After the given reaction time, the partial pressure of ${\text{H}}_{\text{2}}$ has to be identified.
