For irreversible A → P under one fixed kinetic regime, which statements are incorrect? Assume no reverse reaction, no catalyst deactivation and constant temperature and volume.

Question

TestHub · Accepted Answer

Molecularity counts reacting entities in one elementary event, so it must be a positive integer; A is incorrect. First-order rate k[A] falls with [A], making B correct. Zero-order rate is k while its kinetic regime persists and reactant remains, making C correct under the assumptions. Overall stoichiometry does not determine the experimental order of a general reaction, so D is incorrect. The requested selections are the incorrect statements only.
