Question

For the sequential reactions: A → B → C (K1 = K2 = 0.02 min^-1), the initial concentration of 'A' was 0.2 M and initially 'B' and 'C' were absent. The time at which the concentration of 'B' becomes maximum and the maximum concentration of 'B' are, respectively,

Prashant Kotian · Accepted Answer

Correct answer: A. For sequential reaction where K1 = K2 = k, t_max = 1/k = 1/0.02 = 50 min. [B]_max = A0 / e = 0.2 / e. Therefore, correct answer is A.
