Chapter 16.2, Problem 16.1AFP

Interpretation Introduction

Interpretation:

The given reaction has to be balanced and the rate in terms of the change in concentration with time for each substance has to be expressed.

Concept introduction:

Rate of reaction: The rate of the reaction for any interval of time can be expressed as the negative of the change in concentration of reactant by the change in time or positive sign of the change in concentration of product by change in time.

$\begin{array}{l}\text{ Reaction: R}\to \text{P}\\ \\ \text{Rate}\text{of}\text{decomposition}\text{of}\text{Reactant = }\frac{\text{- change in }\left[\text{R}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{R}\right]}{\text{Δt}}\\ \\ \text{Rate}\text{of}\text{formation of product = }\frac{\text{+ change in }\left[\text{P}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{P}\right]}{\text{Δt}}\end{array}$
