Question

Faraday's constant is defined as

• A. charge carried by one electron
• B. charge carried by one mole of electron
• C. charge required depositing one mole of substance
• D. charge carried by two moles of electron

Answer 1

Answer: (B)

charge carried by one mole of electron

Answer 2

Charge carried by one electron
$1.6 \times 10^{-19} C$
$\therefore$ Charge carried by $6.023 \times 10^{23}$ electrons (ie, $1$ mol electrons)
$=1.6 \times 10^{-19} \times 6.023 \times 10^{23}$
$=96368=1\, F$
Thus, Faraday constant $(F)$ is defined as charge carried by one mole of electrons.
