I'm enrolled in a very difficult advanced electrochemistry class. We have homework due tomorrow. I'm very stressed and need help. I will be willing to pay for help through paypal. Msg me if interested

ok, thanks! I just don't understand this question. I think it involves the nernst equation

Consider the electrode/water based solution interface Pt/Ag+ (0.0001 M), Cu2+ (0.01M),
Pb2+ (0.1 M), HClO4 (1 M) and write the equation (s) for the electrode reaction (s) that
occur (s) at applied potentials of:
a) 1.4 V
b) 0.6 V
c) 0.2 V
d) – 0.6 V

Consider the various redox reactions that could occur, e.g. the reduction of Ag⁺ to metallic Ag. Look up the standard electrode potential for this couple, and apply the Nernst equation to find the electrode potential at the given concentration of 0.0001 M Ag⁺. At applied potentials lower than this, Ag⁺ will be reduced to Ag.
Repeat with the other species.
