Determine the order of reaction with respect to A\mathrm{A} and and also calculate the half-life of A\mathrm{A} in the reaction.
View answer and explanation
Correct option: A
1.3861.386
The correct answer is 1.386 because the reaction is first order with respect to A and zero order with respect to B, allowing calculation of the rate constant and subsequently the half-life.
