Problem Details

One process catalyzed by NADH dehydrogenase is

NADH + H+ + ubiquinone ⇌ NAD+ + ubiquinol

The standard reduction potentials for the half-reactions are given in the table:


Oxidant                                    Reductant                E0'(V)       

ubiquinone + 2H+ + 2e-              ubiquinol                  0.045

NAD+ + H+ 2e-                             NADH                       -0.32


Calculate ΔE0' for the reaction as shown:
