$A$ reaction that takes place with the absorption of energy is

Which of the following reactions takes place at the anode during the electrolysis of molten $NaCl$?

Explain: Oxidation of $Cl^{-}$ ion is carried out near the anode when electrolysis of aqueous (concentrated) $NaCl$ solution is carried out using an inert electrode.

The use of electrolysis is:

The charge required for the reduction of $1 \ mol$ of $MnO_4^-$ to $MnO_2$ is ............ $F$.

In the process of electrolysis,the current is carried out inside the electrolyte by
