Oxidation-reduction reactions with positive standard redox potential (E⁰’) have
(A) positive ΔG⁰
(B) negative ΔG⁰
(C) positive ΔE⁰’
(D) negative ΔE⁰’

Answer

Answer: (B) negative ΔG⁰
A positive standard redox potential (E⁰’) indicates that the reaction is favorable and will proceed spontaneously. This corresponds to a negative ΔG⁰ (Gibbs free energy change). Positive ΔE⁰’ is associated with negative ΔG⁰.
