a) ans is
if the left-hand electrode turns out to be the cathode, then the reverse of the cell reaction is spontaneous.) To write the cell reaction corresponding to a cell diagram, the right-hand half reaction is written as a reduction, and the left-hand half-reaction, written as an oxidation, is added to it.
