Which of the following statements is false?
a) the rate of zero order reactions are not dependent on concentration.
b) the half life of a first order reaction is dependent on the initial concentration of reactant.
c) the average rate of a reaction decreases during a reaction.
d) it is not possible to determine the rate of a reaction from its balanced equation.

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.
