#Question id: 465

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. Structure and Function of Biomolecules

  1. This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than +0.30 V.

  2. This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential greater than -0.0V 

  3. This half-reaction will proceed if it is coupled to another half-reaction that has a standard reduction potential less than -0.30 V.

  4. It doesnʹt matter what half-reaction this is coupled with, it will proceed spontaneously.
