Problem
A chemist analyzes a sealed reaction vessel and finds that the instantaneous ratio of product to reactant concentrations is considerably larger than the ratio observed once the system has reached equilibrium at the same temperature. Which statement best predicts what will happen next?
(a) The reaction will proceed predominantly in the forward direction to form more products.
(b) The direction of change cannot be predicted without knowing the numerical value of K.
(c) The reaction will proceed predominantly in the reverse direction to form more reactants.
(d) No net change will occur because the system is already at equilibrium.
