Question

A flask contains a mixture of compound A and B. Both compounds decompose by first order kinetics. The half-lives for A and B are 300 s and 180 s, respectively. If the concentrations of A and B are equal initially, the time required for the concentration of A to be four times that of B (in s) is : (Use ln 2 = 0.693) t t

(A) 180
(B) 300
(C) 120
(D) 900
