MCQ
The relation between faraday constant $F$, electron charge $e$ and avogadro number $N$ is
  • A
    $F=N / e$
  • $F=N e$
  • C
    $N=F^2$
  • D
    $F=N^2 e$

Answer

Correct option: B.
$F=N e$
(b) Faraday constant $=1$ mole electron charge $=\mathrm{Ne}$$=6.02 \times 10^{23} \times 1.6 \times 10^{-19}=96500$
