Question

Write the distinction between electrochemical cell and electrolytic cell

Answer 1

Electrochemical cells
* an electrochemical cell converts chemical energy to electrical energy.
*it is based upon the redox reactions which are spontaneous.
*the chemical change occuring in the 2 beakers are different.
*anode is negative
*cathode  is positive

Electrolytic cells
*converts electrical energy to chemical energy
*the reactions are non spontaneous and starts only when energy is supplied.
*only one chemical compound undergoes decomposition
*anode is positive
*cathode is negative.

hope this helps u......
