Consider the following four statements about equilibrium constants.
I. An equilibrium constant equal to 1 indicates that the forward reaction has stopped.
II. An equilibrium constant much greater than 1 signifies that products predominate at equilibrium.
III. An equilibrium constant much less than 1 indicates that the reaction mixture is at dynamic equilibrium but largely reactant-favoured.
IV. The numerical value of an equilibrium constant changes if all species concentrations are halved at constant temperature.
Which combination of statements is/are correct?
a) I and II only
b) II and III only
c) II and IV only
d) II only
