For the first-order reaction, A $\rarr$ products, if half of the initial concentration of A reacts in 20 min, then the remaining half will completely react in the next 20 min.

Question

Quizplus · Accepted Answer

For a first-order reaction, the time it takes for half of any given amount of reactant to decompose (half-life) is constant and does not depend on the initial concentration. Therefore, after the first half reacts in 20 minutes, the remaining half will also take 20 minutes to reduce to half of its amount, not to completely react.
