Question

For a first order reaction, the half-life period (t_1/2) is ______.

Options

• proportional to the initial concentration.

• inversely proportional to the initial concentration.

• proportional to the square root of the initial concentration.

• independent of the initial concentration.

Answer 1

For a first order reaction, the half-life period (t_1/2) is independent of the initial concentration.

Explanation:

For a first-order reaction, the half-life period is constant. The half-life of a reaction is the time in which the concentration of a reactant is reduced to one-half of its initial concentration. It is represented as (t_1/2).
