Problem
A student makes four assertions about the meaning of an equilibrium constant that is much less than 1.
Which assertion is correct?
(a) The reverse reaction has a lower activation energy than the forward reaction.
(b) At equilibrium, the concentration of reactants exceeds that of products.
(c) At equilibrium, the rate of the reverse reaction exceeds that of the forward reaction.
(d) A catalyst would increase the equilibrium constant, making it closer to 1.
