Question

Half-life period of a zero order reaction is:

• A. directly proportional to initial concentrations of reactants
• B. independent of initial concentrations of reactants
• C. inversely proportional to initial concentrations of reactants
• D. inversely proportional to the square of initial concentrations of reactants

Answer 1

The correct option is A directly proportional to initial concentrations of reactants

Half life of zero order reaction is given by $t_{\frac{1}{2}}=\frac{a}{2k}$

where 'a' is initial concentration of reactants.

$\therefore$ half life of zero order reaction is directly proportional to the initial concentration of reactants.
