If the standard reduction potential of a certain half-reaction is -0.30 V, which statement below is true for this half-reaction to proceed as a reduction?

#Unit 1. Molecules and their Interaction Relevant to Biology

This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than +0.30 V.
This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than -0.30V
This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential less than -0.30 V.
It doesnʹt matter what half-reaction this is coupled with, it will proceed spontaneously.
