In a galvanic cell

Options

A. oxidation occurs at cathode
B. reduction occurs at anode
C. electrical energy produces chemical reaction
D. chemical reaction produces electrical energy

Answer

D

Explanation

A galvanic cell is an electrochemical cell that con-verts the chemical energy of a spontaneous redox reaction into electrical energy. In this device the Gibbs energy of the spontaneous redox reaction is converted into electrical work which may be used for running a motor or other electrical fadfets like heater, fan, geyser, etc.
The electrode at which oxidation takes place is called the anode while the electrode at which reduction takes place is called the cathode.
