Chapter 15, Problem 35E

Interpretation Introduction

Interpretation:

The forms of integrated rate law, differential law should be determined along with the value of rate constant for the following reaction at $225°C$ . The concentration of ${\text{NO}}_{\text{2}}$ should be calculated at $\text{2}\text{.70}\times {\text{10}}^4\text{ s}$ after start of the reaction.

  ${\text{NO}}_2\text{(g)+CO(g)}\to {\text{NO(g)+CO}}_2(\text{g})$

Concept Introduction:

Rate Law can be expressed as an integrated rate law and a differential rate law.

Differential Rate Law: This describes the change in the concentrations of reactant as a function of time.

Integrated Rate Law: This describes the initial concentrations and the measured concentration of one or more reactants as a function of time.
