Use the reaction to answer the question.

3MnO₄ ²⁻ + 4H⁺ ⇄ 2MnO₄⁻ + 2H₂O + MnO₂(s)

How would adding MnO₄²⁻ ions affect this reaction?

a) The equilibrium would shift to the right, and the concentration of MnO₄⁻ ions would increase.

b) The equilibrium would shift to the left, and the concentration of H₂O would decrease.

c) The equilibrium would shift to the left, and the concentration of H+ ions would increase.

d) The equilibrium would shift to the right, and the concentration of MnO₂ would decrease.

1 answer

Adding MnO₄²⁻ ions would shift the equilibrium to the right, and the concentration of MnO₄⁻ ions would increase. Therefore, the correct answer is (a).
