Problem
Which of the following statements most accurately contrasts the magnitude of an equilibrium constant with the speed of a reaction?
(a) A large equilibrium constant implies both a product-favoured equilibrium position and a fast forward reaction rate.
(b) The magnitude of the equilibrium constant indicates the relative concentrations of species at equilibrium but does not provide information about reaction rates.
(c) If two reactions have identical equilibrium constants, they must reach equilibrium in the same amount of time under identical conditions.
(d) The magnitude of the equilibrium constant can be used to calculate the rate constant for the forward reaction at a given temperature.
