Using the following standard reduction potentials,
Fe3+(aq) + e- →Fe2+(aq) E° = +0.77 V
Ni2+(aq) + 2 e- →Ni(s) E° = -0.23 V
calculate the standard cell potential for the galvanic cell reaction given below, and determine whether or not this reaction is spontaneous under standard conditions.
Ni2+(aq) + 2 Fe2+(aq) → 2 Fe3+(aq) + Ni(s)
a) E° = -1.00 V, spontaneous
b) E° = +1.00 V, nonspontaneous
c) E° = +1.00 V, spontaneous
d) E° = -1.00 V, nonspontaneous
