Nitric oxide reacts with bromine at elevated temperatures according to the equation, 2 NO(g)+ Br₂(g)$\rarr$ 2 NOBr(g).The experimental rate law is: rate = k[NO][Br₂]. The half-life of either of the reactant species is independent of its concentration and is equal to 0.693/k.

Question

Quizplus · Accepted Answer

The half-life being independent of concentration is characteristic of a first-order reaction, but the given rate law indicates a second-order reaction, as it depends on the concentration of both NO and Br2.
