ELECTROCHEMICAL PRINCIPLE OF METALLURGY

Options

A. In simple electrolysis, the `M^(n^(+))` ions are discharged at positive electrodes
B. More reactive metals have large neagative values of the electrode potential, thus their reducttion is difficult
C. Positive `E^(0)`, results in negative `DeltaG`, the reaction would be spontanous, thus less reactive metal will come out of the solution and nore reactive metal will go into the solution
D. If for a cell reaction `E^(0)` is negative, the value of `DeltaG`, for the cell reaction would be +ve and the reaction would not be feasible.
