Concept introduction:
- Zero-order reaction- for this,
rate of reaction is independent of the concentration.
And the graph of zero order reaction is-
- The first order reaction is the one in which the rate is directly proportional to the concentration of one of the reactant.
And half-life is
Integral rate law for first order reaction is −
and
- The second order reaction is the one in which the rate is directly proportional to the square of the concentration of one of the reactant.
