What is the mathematical formula for the half-life () of a zero-order reaction? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For a zero-order reaction, the integrated rate law is $[A]_t = [A]_0 - kt$. At the half-life ($t = t_{1/2}$), $[A]_t = [A]_0 / 2$. Substituting this gives $[A]_0 / 2 = [A]_0 - k t_{1/2}$, which rearranges to $t_{1/2} = [A]_0 / 2k$.
