When Cu reacts with AgNO3 solution, the reaction takes place is:
oxidation of Cu
reduction of Cu
oxidation of Ag
reduction of NO
A.
oxidation of Cu
Cu is placed above Ag in electrochemical series, hence it can replace Ag from its salts solution. Therefore the reaction occur as follows:
For a cell involving one electron E°cell = 0.59 V at 298 K, the equilibrium constant for the cell reaction is :[ Given that .

For the cell reaction
2Fe3+ (aq) +2l-(aq) → 2Fe2+(aq) + I2(aq)
E= 0.24V at 298 K. The standard Gibbs energy (ΔrGΘ) of the cell reaction is:
