Question

Assertion (A): The half-life for a zero-order reaction is independent of the initial concentration of the reactant.

Reason (R): For a zero-order reaction, Rate = k

Select the most appropriate answer from the options given below:

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

The half-life for a zero-order reaction is `t_(1//2) = [R_0]/(2k)` where [R₀] is the initial concentration of the reactant.
