(Answered) Identify the reaction at the anode reaction at the cathode

Academics

Identify the reaction at the anode, reaction at the cathode, the overall reaction, and approximate potential required for the electrolysis of the following molten salts. Assume standards states and tha the standard reduction potentials in Appendix L are the same as those at each of the melting points. Assume the efficiency is 100%.

(a) CaCl2

(b) LiH

(d) CrBr3

How can I determine which reaction will be at the anode and which will be on the cathode side?

Is there a way to tell whether the reaction is going to under oxidation or reduction?
