Overpotential

Postby Rida Ismail 2E » Mon Mar 02, 2020 11:36 pm

Can someone explain the idea of overpotential in the context of why they would need to reduce the overpotential in order to increase efficiency electrolytic processes?

Overpotential is additional energy that needs to be added in order to power an electrolytic cell. By decreasing overpotential, we decrease the amount of electrical energy that has to be supplied to the cell in order for the chemical reactions to occur which would make it more efficient.
