Le Chatelier's principle. I only need to know which direction the reaction will flow by diluting the reaction with water. My professor said that there will be no shift, but I would like an explanation why.

9. The following chemical reaction is run until it reaches equilibrium. Use the Law of Mass Action (LeChetlier's Principle) to predict the outcome of each of the following changes to the system. H3C2O2H + H+ + H3C202 Action System Response Add more H3C202H Remove H+ Remove some H3C2O2H Add more H3C202 Dilute reaction with water
