Differences between electrolytic cells and voltaic cells
Posted: Thu Oct 28, 2021 8:24 am
Voltaic Cells
a)Do not require a power source.
b)Convert chemical potential energy into electrical energy.
c)The redox reaction is spontaneous. (The cell potential is positive and the change in Gibb's free energy is negative)
d)The reaction with the lower standard reduction potential is utilized as the anode, and the reaction with the high standard reduction potential is utilized as the cathode.
Electrolytic Cells
a)Require a power source.
b)Require work by converting electrical energy to chemical potential energy.
c)The redox reaction is non-spontaneous. (The cell potential is negative and the change in Gibb's free energy is positive)
d)The reaction with the lower standard reduction potential is utilized as the cathode, and the reaction with the high standard reduction potential is utilized as the anode.
Are the above differences correct? especially d) part of the both cell features
