How can one determine that a redox reaction will be nonspontaneous?

Answer:
A redox reaction is spontaneous if the standard electrode potential for the redox reaction, Eo(redox reaction), is positive. ...
If Eo(redox reaction) is positive, the reaction will proceed in the forward direction (spontaneous)
Explanation:
thank me later
Answer:
C. The reduction potential plus oxidation potential is negative.

it was right lol
