Using the Following Standard Reduction Potentials

question 78

Multiple Choice

Using the following standard reduction potentials,
Fe³⁺(aq) + e^- → Fe²⁺(aq) E° = +0.77 V
Ni²⁺(aq) + 2 e^- →Ni(s) E° = -0.26 V
Calculate the standard cell potential for the 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° = - 1.03 V,nonspontaneous
• B)E° = - 1.03 V,spontaneous
• C)E° = + 1.03,nonspontaneous
• D)E° = + 1.03,spontaneous
