For a given reaction half life period was found to be directly proportional to the initial concentration of the reactant. The order is

General for of 1 2 t 1-n 1 0 2 t A If 1 0 2 t A i.e., 1- n = 1 n 0 107. The half-life period of a zero-order reaction is (a) directly proportional to initial concentration (b) inversely proportional to initial concentration (c) independent of initial concentration (d) proportional to the square of initial concentration. General relation between 1 2 t and concentration is 1-n 1 2 t a Where, n is order of reaction, a initial concentration. For zero-order reaction, 1 1 2 t a
