MUST Provide reason for each option you choose

A voltaic cell is assembled at 298K with Fe (s) and Fe(NO3)2(aq) in one compartment and Au (s) and Au(NO3)3(aq) in the other. An external wire connects the two electrodes, and a salt bridge containing KNO3 connects the two solutions,

Fe2+(aq) + 2 e  à  Fe (s) E° = –0.44 V

Au 3+(aq)  +  3 e à  Au (s) E° = 1.50 V
