Quizplus · Accepted Answer

According to Le Chatelier's principle, a system at equilibrium will adjust in a way that opposes any stressor or change in conditions applied to it.

A) Decreasing [MN₂+] will shift the equilibrium to the right to restore the concentration of Mn₂+ ions.

B) Decreasing [OH-] will shift the equilibrium to the right to restore the concentration of OH- ions.

C) Decreasing pH (increasing [H+]) will shift the equilibrium to the right to counteract the increase in H+ ions by consuming them in the reaction.

D) Adding nitric acid (HNO3) will also decrease the pH (increase [H+]) and provide NO3- ions for the reaction to proceed to the right.

Therefore, all of the listed changes will shift the equilibrium to the right, increasing the concentration of MN₂+ and OH- ions.
