A → B The above reaction is of zero order. Half life of this reaction is 50 min . The time taken for the concentration of A to reduce to one-fourth of its initial value is min . (Nearest integer)

Correct answer

0

Step-by-step solution

The integrated rate equation of zero order reaction is kt = A 0 - A t Assume reaction starts with 1 mole A t 1 / 2 = a 2 k , K = 1 2 × 50 For 75 % completion A 0 = a ,   A t = a 4 a - a 4 = kt t = 3 4 a k = 3 4 × 100 a = 75   min
