In the first order reaction A k k_1 B, the initial concentration of A and B are [A]o and 0 respectively. At equilibrium the concentration of A and B becomes [A]e and [B]e respectively. Derive an expression for the time taken by B to attain a concentration equal to 0.5[B]e. For this reaction at 75 C, let k 1.2 x 10-3s- and k-1 = 3.3 10- min. Find the time required to produce B to half of its equilibrium concentration. In the first order reaction A k k_1 B, the initial concentration of A and B are [A]o and 0 respectively.
