Estimate the mean and individual activity coefficients for a 0.25 molar solution of macl2 in water using the debye-hückel and davies equations. an experimental value of the mean activity coefficient is 0.53

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

Consider the reduction reactions and their equilibrium constants. cu+(aq)+e−↽−−⇀cu(s)pb2+(aq)+2e−↽−−⇀ pb(s)fe3+(aq)+3e−↽−−⇀fe(=6.2×108=4. 0×10−5=9.3×10−3 cu + ( aq ) + e − ↽ − − ⇀ cu ( s ) k =6.2× 10 8 pb 2 + ( aq ) +2 e − ↽ − − ⇀ pb ( s ) k =4.0× 10 − 5 fe 3 + ( aq ) +3 e − ↽ − − ⇀ fe ( s ) k =9.3× 10 − 3 arrange these ions from strongest to weakest oxidizing agent.
