Write the schematic representation and reaction of the cell composed of SHE and cadmium electrode. Deduce the half-reaction potential of the cadmium electrode from the E^°_cell= - 0.403 V. Is the reaction spontaneous or not? Why or why not? If it is not spontaneous, how should the schematic representation be written to make it spontaneous?
