Answer
since the capacitor is discharging, the plate with the higher potential is the left plate, and the plate with a lower potential is the right plate since the current flows from the plate with the higher potential. Which means the electric field between the plates is rightward, since the electric field lines goes from the higher potential plate to the lower potential plate, as shown in the figure.
