MHT CET 2026 Chemistry question

Identify correct statement regarding order of reaction from following.

(A)Rate of zero order reaction depends on initial concentration of reactant.
(B)Decomposition of acetaldehyde is a first order reaction.
(C)Half life of first order reaction is independent of initial concentration of reactant.Correct
(D)Half life of zero order reaction is independent of initial concentration of reactant

Answer: (C)

Solution

Evaluate each statement. (A) For a zero-order reaction, rate , which is constant and independent of concentration, so (A) is false. (B) The thermal decomposition of acetaldehyde, CH_3CHO \rightarrow CH_4 + CO, follows the rate law , i.e. order 3/2, not first order, so
