🤓 Based on our data, we think this question is relevant for Professor Lin's class at UCLA.

Solution: 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.    

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.
