In an electrolytic cell, the magnitude of the standard cell potential is the: a. minimum voltage that must be supplied for a redox reaction to occur
b. maximum voltage that willallow the redox reaction to occur
c. always equal to Eanode - Ecathode
d. none of the above

a. minimum voltage that must be supplied for a redox reaction to occur

c. always equal to Eanode - Ecathode

Explanation:

In an electrolytic cell;  The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e )

As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.

Therefore, option a and c are both correct.

the answer is true. hope it .
