To Decide Whether a Reaction Mixture Is at Equilibrium, a Student

To decide whether a reaction mixture is at equilibrium, a student determines the value of Q, the reaction quotient, and finds that it is less than K. Therefore, the mixture is

A) at equilibrium, since there is as much reaction as required.
B) not at equilibrium, and will react to the right, to increase the amounts of products.
C) not at equilibrium, and will react to the left, to increase the amounts of reactants.
D) not at equilibrium, and will react to the right, to increase the amounts of reactants.
E) not at equilibrium, and will react to the left, to increase the amounts of products.
