Q. If the half-time for a particular reaction is found to be constant and independent of the initial concentration of the reactants, then the ratio is of
A) First order
B) Zero order
C) Second order
D) None of these
Explanation

For first order reaction the half-life period is independent of the initial concentration of the reactants.
$t_{1/2} = \frac{0.693}{k}$
