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
Correct Answer: B
Solution :
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.
