When Keq of a reaction = 1,then
A)the forward reaction is faster than the reverse reaction.
B)the reverse reaction is faster than the forward reaction.
C)the forward and reverse reaction rate constants are equal.
D)more products are formed than reactants.
E)fewer products are formed than reactants.

Question

Quizplus · Accepted Answer

When Keq = 1, it means that the concentrations of the reactants and products are at equilibrium and are equal. This also means that the ratio of the rate constants for the forward and reverse reactions is equal, as described by the equilibrium constant expression. Therefore, choice C is the correct answer. Choices A and B suggest that one reaction is happening faster than the other, which is not the case at equilibrium. Choices D and E suggest that there is a preference for one side of the reaction to occur, which is also not the case at equilibrium.
