An electrochemical cell has the following standard cell notation.

mg(s) | mg^2+ (aq) || aq^+(aq) | aq(s)

what is the standard potential for the cell?

is this a spontaneous or non spontaneous reaction? explain your answer.

is this a galvanic cell or an electrolytic cell? explain your answer.

The standard potential for the cell is: 3.17 V

The reaction is spontaneous

It is a galvanic cell

Explanation:

The half-reactions for each process are:

Oxidation: Mg(s) -> Mg^2+ (aq) + 2e^-   E^0 = 2.37

Reduction: Ag^+ (aq) + 1e^-  -> Ag(s)      E^0 = 0.8

The standard potential for the cell is:

E^0 cell = E^0 reduction + E^0 oxidation = 2.37 + 0.8 =  3.17 V

The reaction is spontaneous because the standard potential for the cell is positive.

It is a galvanic cell. In a galvanic cell, spontaneous redox processes occur allowing the continuous flow of electrons through the conductor, whereas, in an electrolytic cell, the non-spontaneous redox reactions are promoted by an external source of current.
