Chapter 13, Problem 13.135CP

Interpretation Introduction

Interpretation:

Concentrations of NO, O_2,NO₂after 100.0 s in the reaction $2N{O}_{(g)}+O_2{}_{(g)}\to 2N{O}_2{}_{(g)}$ can be calculated from the given initial concentration.

Concept introduction:

The rate is directly proportional to the concentration of the first reactant. When the concentration of the reactant doubles, the rate also doubles. Because thereaction is third-order, the sum of the exponents in the rate law must be equal to three.

To determine:

The concentrations ofNO, O_2,NO₂after 100.0 s in the reaction $2N{O}_{(g)}+O_2{}_{(g)}\to 2N{O}_2{}_{(g)}$
