Question

consider the over all reaction wherein a pair of electrons passes from NADH to lipoic acid

a. the overall net potential for this reaction is _______ V.

b.the equilibrium constant for this reaction is ______.

c. based on the given half reactions, the strongest oxidizing agent is ______ while the strongest reducing agent is____.

NAD+ + H+ + 2e²
fumarate + 2H+ + 2e7
pyruvate + 2H+ + 2e
lipoic acid + 2H+ + 2e
NADH
E°' = -0.32 V
succinate
Eo¹=-0.03 V
lactate
E' = -0.19 V
dihydrolipoic acid E°¹ = -0.29 V
