Using the Following Standard Reduction Potentials $\quad$ $\quad$ Fe³⁺(aq)+ E^- →Fe²⁺(aq)E° = +0

Using the following standard reduction potentials,
$\quad$$\quad$ Fe³⁺(aq) + e^- →Fe²⁺(aq) E° = +0.77 V
$\quad$$\quad$ 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.

A) E° = -1.00 V,nonspontaneous
B) E° = -1.00 V,spontaneous
C) E° = +1.00 V,nonspontaneous
D) E° = +1.00 V,spontaneous
