In an electrolytic cell, what processes occur at the cathode and anode respectively?

The cell shown in the image below is used to commercially produce Sr via electrolysis from a molten salt (the electrolyte), such as SrCl₂. Remember that in an electrolytic cell, which is the opposite to what we see in batteries, the anode is given the "-" sign and the cathode is given the "+" sign. What is the half-reaction at the anode of the electrolytic cell?

Draw a cell setup for the electrolysis of molten ZnCl₂ and indicate the direction of the flow of electrons.
