The decomposition of SOCl₂ is first-order in SOCl₂. If the half-life for the reaction is 4.1 hr, how long would it take for the concentration of SOCl₂to drop from 0.36 M to 0.045 M?

Question

Quizplus · Accepted Answer

For a first-order reaction, the time taken for the concentration to drop to a certain level can be calculated using the formula t = (t₁/₂ / 0.693) * ln([A]₀/[A]). Given the half-life (t₁/₂) is 4.1 hr, [A]₀ = 0.36 M, and [A] = 0.045 M, the time t is approximately 12 hours.
