Question

Which of the following is a universal constant ?

• A. Farad
• B. Chemical equivalent (CE)
• C. Electrochemical equivalent (ECE)
• D. Faraday

Answer 1

The correct option is D Faraday

Faraday represent the amount of electric charge carried by one mole or Avogadro's number of electrons. it can be derived by dividing the Avogadro's constant or the number of electrons per mole by number of electrons per coulomb.

Hence we can see when it is derived it does not depend upon any such factor which could change at any time . that's why Faraday's constant is always considered as universal Constant . it is symbolized by the italic letter F.
