The Faraday constant
The Faraday constant
Options
- Ais a universal constant.
- Bdepends on the amount of charge transferred through the electrolyte.
- Cdepends on the current passing through the electrolyte.
- Ddepends on the quantity of the electrolyte.
Correct answer
A. is a universal constant.
Step-by-step solution
The Faraday constant is defined as the magnitude of electric charge per mole of electrons.
where is the Avogadro constant and is the elementary charge. Since both and 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.
