Homework Answers
Rate:
The rate of a chemical reaction is defined as the change in concentration of a substance (reactant or product) per unit of time. It is expressed as
.
Half-life:
It is defined as the time needed to minimize the initial concentration to half. It is denoted by the symbol
.
Significant figures:
The term significant figures refer to the meaningful digits in it.
For a first order reaction,
For a first order reaction, the half-life time is independent of the initial concentration of the substrate.
