At a certain temperature,bromine and nitric oxide react to form nitrosyl bromide: Br₂(g) + 2 NO(g) ⇌ 2 NOBr(g) .
When initial amounts of Br₂,NO,and NOBr are mixed,the concentration of NOBr increases.Which statement below is true?

Question

Quizplus · Accepted Answer

Since the concentration of NOBr increases, this means that the reaction proceeds towards the formation of NOBr. Therefore, the reaction quotient Q must be less than the equilibrium constant Kc. Therefore, Kc > Q, which is equivalent to option B. Option A and C can be ruled out based on this reasoning. Option D is incorrect as there is enough information given in the question stem to make a conclusion about Kc and Q.
