For a redox reaction at 298 K that has a positive standard cell potential E∘>0, which statement about the equilibrium constant K for the reaction is most accurate?
a) K=1 because the reaction quotient Q equals 1 under standard conditions.
b) K cannot be determined without knowing the initial concentrations of all species.
c) K>1 because the forward reaction is thermodynamically favored at standard conditions.
d) K<1 because a positive standard potential indicates that the reactants are more stable at equilibrium.
