Problem
A gaseous reaction at 298 K has an equilibrium constant of Kc=7.5×108. Which statement best describes the composition of the equilibrium mixture?
(a) Products and reactants are present in comparable, significant amounts.
(b) It consists almost entirely of products, with negligible amounts of reactants.
(c) The reaction cannot reach equilibrium because the value of Kc is too large.
(d) It consists almost entirely of reactants, with negligible amounts of products.
