The Faraday constant

The Faraday constant

Options

  1. Ais a universal constant.
  2. Bdepends on the amount of charge transferred through the electrolyte.
  3. Cdepends on the current passing through the electrolyte.
  4. Ddepends on the quantity of the electrolyte.

Correct answer

A. is a universal constant.

Step-by-step solution

The Faraday constant FF is defined as the magnitude of electric charge per mole of electrons.

F=NA×eF = N_A \times e

where NAN_A is the Avogadro constant and ee is the elementary charge. Since both NAN_A and ee are universal constants, the Faraday constant is also a universal constant. It does not depend on the amount of charge transferred, the current passing through the electrolyte, or the quantity of the electrolyte.
