Chapter 11, Problem 11.22PAE

Interpretation Introduction

Interpretation:

The rate measured in an initial rate experiment must be classified as either average or instantaneous rate

Concept Introduction:

• Chemical reactions proceed at a certain rate which is represented in terms of the change in concentration over a certain period of time.
• The rate can be expressed either in terms of a decrease in concentration of the reactants or an increase in the concentration of products.
• Average rate of a reaction can be defined as the difference in the concentrations measured at two different times whereas, instantaneous rate can be defined as the rate of a reaction at a particular instant in time.
