Question

Which of the following statements is FALSE?The rate of a first order reaction is dependent on concentraion.The half life of a zero order reaction is dependent on concentration.The half life of a second order reaction is not dependent on concentration.The rate of second order reactions is dependent on concentration.None of the statements are FALSE.

Answer 1

The false statement is: The half life of a zero order reaction is dependent on concentration. In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants.

Step-by-step explanation:

The false statement is: The half life of a zero order reaction is dependent on concentration.

In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. This means that the half-life, which is the time it takes for half of the reactant to be consumed, does not depend on the initial concentration of the reactant.

In contrast, for first-order reactions, the rate is dependent on the concentration of one reactant and the half-life remains constant regardless of the concentration. For second-order reactions, the rate is also dependent on the concentration, but the half-life decreases as the concentration increases.
