Answer & Solution

Correct Answer

(B) 19300 C

Step-by-step Solution

Detailed explanation

During electrolysis of molten NaCl , the following reaction takes place at anode:
\(2 \mathrm{Cl}^{-} \longrightarrow \mathrm{Cl}_2+2 \mathrm{e}^{-}\)
1 mole of \(\mathrm{Cl}_2\) is liberated with 2 moles of electrons.
\(\therefore 0.1 \text { mole of } \mathrm{Cl}_2 \text { will be liberated with }\)\(0.2 \text { moles}\)\(\text { of electrons.}\)
