Question

What is the numerical value of one Faraday in Coulombs?

• A. 96587
• B. 96487
• C. 99500
• D. 6.023

Answer 1

The Correct Option is A

One Faraday, in terms of electrochemistry, is defined as the charge of one mole of electrons. This is calculated using the charge of a single electron and Avogadro's number.

The charge of one electron is approximately \(1.602 \times 10^{-19}\) Coulombs. Avogadro's number, which is the number of atoms or molecules in one mole, is approximately \(6.022 \times 10^{23}\). 

The numerical value of one Faraday is the product of these two constants:

Faraday = Charge of one electron × Avogadro's number

Faraday = \(1.602 \times 10^{-19} \) C × \(6.022 \times 10^{23}\)

This calculation yields approximately 96587 Coulombs.

Therefore, the correct answer is: 96587

Answer 2

One Faraday is the amount of electric charge carried by one mole of electrons.

The numerical value of one Faraday in Coulombs is approximately 96,587 C/mol.

This value represents the Faraday constant, which is used in electrochemistry to relate the amount of charge to the amount of substance in a chemical reaction.

Thus, the correct numerical value of one Faraday is 96,587 Coulombs (Option A).
