Chapter 17, Problem 17.9P

Interpretation Introduction

Interpretation:

The average rate reaction for each time interval has to be calculated.

Concept Introduction:

Rate of reaction:  It is defined as change in concentration of species with respect to change in time.  An expression for rate of a general reaction is given by

    $\begin{array}{l}\text{aA + bB }\stackrel{}{\to }\text{cC + dD}\\ \\ \text{Rate}\text{of}\text{reaction}\text{=}\text{-}\frac{\text{1}}{\text{a}}\left(\frac{\text{Δ[A]}}{\text{Δt}}\right)\text{=}\text{-}\frac{\text{1}}{\text{b}}\left(\frac{\text{Δ[B]}}{\text{Δt}}\right)\text{=}\frac{\text{1}}{\text{c}}\left(\frac{\text{Δ[C]}}{\text{Δt}}\right)\text{=}\frac{\text{1}}{\text{d}}\left(\frac{\text{Δ[D]}}{\text{Δt}}\right)\\ \\ \text{Rate}\text{of}\text{reaction}\text{=k}{\text{[a]}}_{\text{0}}{\text{[b]}}_{\text{0}}\\ \\ \text{k}\text{is}\text{rate}\text{constant}\end{array}$
