Solution
Electrode reactions during the electrolysis of molten KCl are as follows:
\[\ce{2Cl^{-}_{ (l)} -> Cl2_{(g)} + 2e^{-}}\] (Oxidation half-reaction at anode)
\[\ce{2K^{+}_{ (l)} + 2e^{-} -> 2K_{(l)}}\] (Reduction half-reaction at cathode)
\[\ce{2K^{+}_{ (l)} + 2Cl^{-}_{ (g)} -> 2K_{(l)} + Cl2_{(g)}}\] (Overall cell reaction)
