Example

Problem: The reaction 2 A → B + C has a Kc of 0.2. The reaction is commenced with initial concentrations [A] = 0.2 M, [B] = 0.2 M and [C] = 0.2 M. In what direction does the reaction occur? 1. Cannot be determined without knowing the temperature. 2. The reaction shifts to the right to reach equilibrium 3. The reaction is already at equilibrium 4. The reaction shifts to the left to reach equilibrium.
