electrochemical cell

spontaneous, positive ecell, produces energy, exothermic

electrolytic cells

non-spontaneous, negative ecell, consuems energy, endothermic

cathode’s terminal in an electrochemical cell

positive

anode’s terminal in an electrochemical cell

negative

cathode’s terminal in an electrolytic cell

negative

positive

overpotential effect

the voltage required for certain soutions is higher than the expected value

overpotential effect cause

slow reaction at the electrode requires extra voltage to speed up rate
