Question

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
