1. In the two half reactions below:

NAD+ + 2H+ +2e- ⥨ NADH + H+         E’0(V) = -0.320 V                 

Fumarate + 2H+ +2e- ⥨ succinate   E’0(V) = +0.031

If you merge these two half reactions into one reaction, what is the voltage change in this reaction (ΔE’0)

1. The table at right is similar to Table 18.1 in that it tabulates standard reduction voltages of half reactions, but in this case the half reactions involve organic molecules important in biochemistry. Note here that the standard conditions are biochemically standard conditions (E°) where T = 25 °C but [H+] = 10-7 M (much less acidic than the [H+] = 1 M in Table 18.1).
