Answer:

The answer to the first question is B) left and the answer to the second question is A) right.

Explanation:

To solve these questions, we must remember that if a change is made to the system, the system will work to reduce that change. In these problems, if we add one reactant/product, the system will shift to use this compound and re-establish equilibrium.

For the first question, H2 is a product. If we add H2 to the system, the equilibrium will shift to the left to decrease the concentration of H2. The second question is the opposite since we are adding CH4 (a reactant). When CH4 is added, the system shifts to the right to decrease the concentration of CH4.
