The standard reduction potentials (E'°) for the following half reactions are given.

Fumarate + 2H+ + 2e– -> succinate E'° = +0.031 V

FAD + 2H+ + 2e– -> FADH2 E'° = –0.219 V

If you mixed succinate, fumarate, FAD, and FADH2 together, all at l M concentrations and in the presence of succinate dehydrogenase, which of the following would happen initially?
