The rate law for the reaction 3A $\to$ 2B is rate = k[A] with a rate constant of 0.0447 hr^-1. What is the half-life of the reaction?

Question

Quizplus · Accepted Answer

The reaction is first-order, as indicated by the rate law rate = k[A]. The half-life for a first-order reaction is given by t₁/₂ = 0.693/k. Substituting the given rate constant k = 0.0447 hr⁻¹, we get t₁/₂ = 0.693/0.0447 = 15.5 hr.
