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 F is defined as the magnitude of electric charge per mole of electrons. F = N_A e where N_A is the Avogadro constant and e is the elementary charge. Since both N_A and e 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.
