What is the electrode potential of a copper wire dipped in 0.1 M CuSO4solution at 25C if the standard electrode potential of copper is 0.34 volt? PLS EXPLAIN how to know the cell reaction in this question ...

The electrode potential can be calculated through Nernst equation.
The reaction taking place is-
Cu2+ + 2e-  Cu    (It is a general electrode reaction)
E(Cu2+|Cu) = EΘ(Cu2+|Cu)-2.303RTnFlog[Cu(s)][Cu2+(aq)]E(Cu2+|Cu) = 0.34 -2.303×8.314×2982×96500log10.1E(Cu2+|Cu) = 0.31V
