5 Questions
Define an electrochemical cell and explain its components.
An electrochemical cell is a device that generates electricity from a spontaneous redox reaction or uses electricity to drive a non-spontaneous redox reaction. It consists of two electronic conductors (anode and cathode), an ionic conductor (electrolyte), and a metal wire (electron conductor) to link the electrodes.
What are the two types of electrochemical cells based on ΔG?
The two types of electrochemical cells based on ΔG are galvanic (voltaic) cells and electrolytic cells.
What is the difference between a galvanic cell and an electrolytic cell?
A galvanic cell generates electrical energy from a spontaneous redox reaction, while an electrolytic cell uses electrical energy to drive a non-spontaneous redox reaction.
