Is it when the standard reduction potential is a positive or negative value that a reduction is spontaneous?

When the standard reduction potential is positive that means the reduction is spontaneous!

A positive standard reduction potential represents a spontaneous reduction reaction.

The standard reaction potential is positive when the reaction is spontaneous.

A reduction is spontaneous when the standard reduction potential is positive.

If the standard reduction potential is positive, then the reduction is spontaneous.

The reduction is spontaneous when standard reduction potential is positive

When standard reduction potential is positive, it is spontaneous.

positive standard reduction potential --> spontaneous reduction

What exactly is the standard reduction potential and why does it have to be positive for the reaction to be spontaneous?

The standard reduction potential is tabulated for compounds with respect to standard hydrogen electrode. It is a measure of the electron-pulling power of the reaction occurring at the electrode. It has to be positive for the reaction to be spontaneous if the right side is cathode, the electrode to where the electrons go; if it is negative, then the reaction would proceed in the reverse direction.

when the standard reaction potential is positive, the rxn will spontaneously proceed in the forward direction

Positive SRP is equivalent to negative delta G so it will be spontaneous.

Positive SRP correlates to a spontaneous reduction!

The reduction is spontaneous when the standard reduction potential is positive.
