Vedclass · Answer

(A) The time required to reduce the concentration of the reactant to half of its initial value is known as the half-life $(t_{1/2})$.For a zero-order reaction,the half-life is given by the formula:$t_{1/2} = \frac{[A]_0}{2k}$where $[A]_0$ is the initial concentration and $k$ is the rate constant.If the initial concentration is doubled,i.e.,$[A]_0' = 2[A]_0$,then the new half-life becomes:$t_{1/2}' = \frac{2[A]_0}{2k} = 2 	imes t_{1/2}$Therefore,the time required for half the reactant to be consumed increases two-fold.

In a zero-order reaction,if the initial concentration of the reactant is doubled,the time required for half the reactant to be consumed:
