A first order reaction takes 16 minutes for its 50% completion. What fraction that would react in 32 minutes from the beginning?

(A)1/2
(B)1/4
(C)1/8
(D)¾Correct

Answer: (D)

Solution

50% completion in 16 min means min (independent of initial concentration for a first-order reaction). In 32 min, half-lives have passed. Fraction remaining , so fraction reacted $= 1 - 1/4 =
