Question

The half-life period of a zero-order reaction is $t_{1/2}$. Which of the following expressions mathematically relates $t_{1/2}$ to the initial concentration $a$ and rate constant $k$?

Answer: B

💡 Solution & Explanation

For a zero order reaction, the integrated rate equation is $x = kt$. At half-life, the amount reacted $x = a/2$. Substituting gives $a/2 = kt_{1/2}$, which rearranges to $t_{1/2} = a/2k$.
