(B)\mathrm{2NO_2CI_{(g)} \to 2NO_{2(g)} + Cl_{2(g)}}
(C)
(D)

Answer: (A)

Solution

An elementary reaction occurs in a single step, so its molecularity equals the number of species colliding and its rate law follows the stoichiometry. is a unimolecular one-step elimination (rate = ), hence (A). Option (B), , is
