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
