Consider the redox reaction 2Fe^2+(aq) + H2O2(aq) + 2H^+(aq) ⟷ 2Fe^3+(aq) + 2H2O(l). If a catalyst is added to the reaction mixture at equilibrium, will the concentration of Fe^3+ increase, decrease or remain the same? Justify your answer mathematically.

A chemistry student wants to determine the concentration of copper(II) ions in a solution using electrochemical methods. The student prepares a copper electrode and a reference electrode, and sets up a cell with the copper electrode immersed in the solution and the reference electrode in the salt bridge. The standard cell potential is measured to be +0.34 V. If the student knows that the reduction of copper(II) to copper occurs at the copper electrode, what is the concentration of copper(II) ions in the solution?
