The reduction potential (E0′) of a substance reflects its tendency to donate or accept electrons. The larger the difference (ΔE0
′) between the reduction potentials of the electron donor and the electron acceptor, __________.A) the greater the change in free energy (ΔG0′), and the less energy is releasedB) the closer the substances are on the electron towerC) the more enzymes will be required to catalyze the reaction(s)D) the greater the change in free energy (ΔG0′), and the greater the energy released
The greater the change in free energy (ΔG0′), and the greater the energy released
Explanation:
Recall that the change in free energy is given by:
∆G°'= nFE°'
But E° is given by E°acceptor - E°donor
Hence the greater the difference between E°acceptor and E°donor, the greater the value of E° and consequently the greater the value of ∆G° and the energy released.
Note: E°acceptor and E°donor refer to reduction potentials of donor and acceptor
