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