Answer:
The half life of a first order reaction is dependent on the initial concentration of reactant. (And. B)
Explanation:
Half-life: It is depends on the order of reaction, different forms for different reaction orders. It can be determined with time, rate constant of the reaction & initial concentration. The time when the concentration of the reactant is decreased to one half of the initial concentration is called half-life of a reaction.
First order reaction: The half-life of the first order reaction is independent of the initial concentration, is a constant.
