The half-life () of an unknown reaction is found to be strictly inversely proportional to the initia — Chemical Kinetics Chemistry Question
Question
The half-life ($t_{1/2}$) of an unknown reaction is found to be strictly inversely proportional to the initial concentration of the reactant ($t_{1/2} \propto [A]_0^{-1}$). What is the order of the reaction?
Answer: C
💡 Solution & Explanation
The general proportionality for half-life is $t_{1/2} \propto [A]_0^{1-n}$. Given that $t_{1/2} \propto [A]_0^{-1}$, equating the exponents gives $1 - n = -1$, which evaluates to $n = 2$ (Second Order).
