Question

When the reversible reaction, N₂+ O₂  2 NO, has reached a state of equilibrium,

Quizplus · Accepted Answer

At equilibrium, the rates of the forward and reverse reactions are equal. Therefore, the statement that "the rate of the forward reaction equals the rate of the reverse reaction" is correct. Choice A is incorrect because reactions still occur, but the rates of the forward and reverse reactions are equal. Choice B is incorrect because the total moles of products does not necessarily have to equal the remaining moles of reactant. Choice C is incorrect because the addition of a catalyst does not cause formation of more NO. Choice E is incorrect because while the rate constants of a forward and reverse reaction are related, they are not necessarily equal.
