Question

An electrochemical cell composed of copper electrode in a solution containing 0.020 M CuNo3 (aq), and a hydrogen electrode in the solution containing 0.010 M Hcl (aq) was set up.
Pt (s)\ H2 (g, 1 bar), HCl (aq, 0.010 M)\\Cu NO3 (aq. 0.020 M)\Cu(s).
What is the balanced half reactions for the chemical processes occuring at the anode and cathode, identify the anode\cathode. Calculate the Ecell.
