Question

Based on the sign of the standard cell potential, ????∘cell, classify these reactions as spontaneous or nonspontaneous as written. assume standard conditions. refer to the list of standard reduction potentials.

Answer 1

For a cell reaction to be sponteanous, the  standard cell potential must be positive.

What is a sponteanous cell reaction?

We define a cell reaction as sponteanous when the value of the standard cell potential is positive. If the standard cell potential is negative then the reaction is not sponteanous.

The question here is incompete but we know that the reactions that are sponteanous will all have a positive  standard cell potential.
