For the well-studied first order experimental reaction , which of the following statements are kinet — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

A is true since $[A]_t = [A]_0 e^{-kt}$. B is true because as temperature increases, $k$ increases via Arrhenius, and $t_{1/2} = 0.693/k$, so $t_{1/2}$ decreases. C is false because first-order half-life is independent of initial concentration/pressure. D is true because fraction left after 8 half-lives is $1/2^8 = 1/256 \approx 0.004$, meaning $99.6\%$ is complete.
