Question

Match the half-life in Column I with the order of reaction in Column II:

Column I:
(A) t1/2 = constant
(B) t1/2 ∝ a
(C) t1/2 ∝ 1/a
(D) t1/2 ∝ 1/a²

Column II:
(P) First order
(Q) Third order
(R) Second order
(S) Zero order

Prashant Kotian · Accepted Answer

Correct answer: A→P; B→S; C→R; D→Q. t1/2 ∝ a^(1-n): (A) 1-n=0 => n=1 → P. (B) 1-n=1 => n=0 → S. (C) 1-n=-1 => n=2 → R. (D) 1-n=-2 => n=3 → Q.
