Chapter 16, Problem 16.1P

Interpretation Introduction

Interpretation:

The variables of a chemical reaction that measured over time to obtain the reaction rate have to be discussed.

Concept introduction:

Reaction: Substances which are mutually involved each other in a chemical process and changed into different substances.

Mechanism of a reaction: The representation of step by step process involved in the chemical process is said to be mechanism of a chemical reaction.

Explanation of Solution

The reaction rate of the chemical reaction:

$\text{Reaction rate}\text{=}\frac{\text{-Δ}\left[\text{R}\right]}{\text{Δt}}.$

During the chemical reaction, the progress of the reaction is determined by determining the concentration of reactant and the product over the course of time.

Therefore, in order to determine the reaction rate, change in concentration of reactants (or products) as functions of time is used.
