Answer 1

Answer:

Electrochemical cell

It is a combination of two half cells containing the same or different electrodes in the same or different electrolytes.

Anode is negative, cathode is positive.

Electrons move from anode to cathode in external circuit.

_________________________________________________

Electrolytic cell

It is a single cell containing the same electrodes present in the same electrolyte.

Anode is positive, cathode is negative.

Electrons enter through cathode and leave through anode.

Answer 2

$\mathcal{\huge{\fbox{\green{AnSwEr:-}}}}$

“Electrochemical cell” is a general term which means a cell(combination of two half cells) which carries out the interconversion of electrical and chemical energy(thus it works on the law of conservation of energy).

In other words an electrochemical cell(as the name indicates) either converts electrical energy into chemical energy or chemical energy into electrical energy)

It has two half cells each having an electrolyte in which electrodes are dipped.Where electrolytes can be of variable strengths depending upon the use.

Electrochemical cells are classified into electrolytic cell and Voltaic cell.

So “Electrolytic cell” is not some different cell from Electrochemical cell rather electrolytic cell is a type of electrochemical cell

Meaning that all electrolytic cells are electrochemical cells but all electrochemical cells are not electrolytic cells

Where electrolytic cell is an electrochemical cell which uses electrical energy to drive a non spontaneous chemical reaction . In other words it converts electrical energy into chemical energy.While,on the other hand…a voltaic cell is an electrochemical cell which convert chemical energy into electrical energy. In other words a spontaneous chemical reaction occurs within the cell and causes the electrons to flow in the external circuit thus giving rise to current.

Spontaneity of reaction can be predicted by applying the concepts of standard Gibbs free energy change,Electrode potentials etc. …

Hope this will help

Good luck
