12. Which of the following terms can be used to describe an electrochemical cell in which a spontaneous chemical reaction generates an electric current? I. an electrolytic cell II. a galvanic cell III.  a voltaic cell 13.Which cell involves a non-spontaneous redox reaction? 14. The nickel-cadmium battery cell has a standard potential of +1.20 V. The cell reaction is 2 NiO(OH)( s ) + Cd( s ) + 2 H 2 O( l ) → 2 Ni(OH) 2 ( s ) + Cd(OH) 2 ( s ). Half reactions: Cd (s) ——>  Cd 2+ (aq) +  2 e – 2Ni 3+ (aq) +  2e – —–>  2Ni 2+ (aq) What is the standard free energy change for this reaction? [ΔG o = – n FE o cell ]
