3. [McQuarrie 25-17] Consider the following equation for a reaction taking place in an electrochemical cell: 2 Cr²+ (aq) + HClO(aq) + H3O+ (aq) = 2 Cr³+(aq) + Cl-(aq) + 2 H₂O(l). Predict the effect of the following changes on the observed cell voltage: Hint: start by writing the cell diagram (line notation) and expression for Q. a. increase in [HCIO] c. increase in pH of cell solution b. increase in size of the inert electrodes d. dissolution of KCl(s) in the cell solution containing Cl-(aq)
