Chapter 20, Problem 90IAE

Interpretation Introduction

Interpretation:

The rate constant for the given reaction involving the decomposition of CO to form CO₂ and C needs to be calculated.

Concept introduction:

The rate of a reaction is expressed in terms of the decrease in the concentration or pressure (in case of gases) over time or in terms of the increase in concentration of products over time.

$\text{Rate = -}\frac{\text{d[Reactants]}}{\text{dt}}\text{ = }\frac{\text{d[Products]}}{\text{dt}}$

For a zero order reaction: Rate = k, where k = rate constant

For a first order reaction: Rate = k[Reactant]

For a second order a reaction: Rate = k[Reactant]2
