Question

The half life period $\left(t_{1/2}\right)$ for the zero order reaction is

• A. Directly proportional to square root of initial concentration of reactant
• B. Directly proportional to initial concentration of reactant
• C. Inversely proportional to initial concentration of reactant
• D. Independent of initial concentration of reactant

Answer 1

The correct option is B Directly proportional to initial concentration of reactant

The half life period for the zero order reaction is $t_{1/2}=\frac{\left[A_0\right]}{2k}$. (where $\left[A_0\right]$ is the initial concentration of reactant)
So, the half life period is directly proportional to the initial concentration of reactant.
