(C) For a zero order reaction,the rate of reaction is independent of the concentration of the reactant.Rate $= -\frac{d[A]}{dt} = k[A]^0 = k$Integrating this expression:$-\int d[A] = \int k dt$$-[A] = kt + C$At $t = 0$,$[A] = [A]_0$,so $C = -[A]_0$.Substituting $C$ back into the equation:$-[A]_t = kt - [A]_0$$[A]_t = [A]_0 - kt$Rearranging for $k$:$kt = [A]_0 - [A]_t$$k = \frac{[A]_0 - [A]_t}{t}$
