which of the following half reactions is most likely to occur at the cathode of an electrolytic cell containing molten nacl at high temperature? you may use the table of reduction potentials.
a. Cl-(aq) + e- → Cl2-(aq) b. 2 H2O(l) + 2 e- → H2(g) + 2 OH-(aq) c. Na+ (aq) + e- → Na(s) d. Cl2(g) + 2 e- → 2 Cl- (aq) e. Na(s) + e- → Na- (aq)
