Vedclass · Answer

(D) For a zero order reaction,the rate law is given by $Rate = k[R]^0 = k$. Integrating this,we get $[R]_t = [R]_0 - kt$. At half-life $(t = t_{1/2})$,the concentration $[R]_t = \frac{[R]_0}{2}$. Substituting this into the integrated rate equation: $\frac{[R]_0}{2} = [R]_0 - kt_{1/2}$. Rearranging for $t_{1/2}$,we get $kt_{1/2} = \frac{[R]_0}{2}$,which simplifies to $t_{1/2} = \frac{[R]_0}{2k}$. Since $k$ is a constant,$t_{1/2} \propto [R]_0$. Therefore,the correct relation is $t_{1/2} \propto [R]_0$.
