I ain't certain about how to solve this question I might be over
thinking it, but it has been bothering me a lot. I think the answer
would E=-0.30 but I ain't certain.
Homework Answers
H2S + Fumarate 
S0 + Succinate
In the above reaction S2- changes to S0 .
While the above tower has reduction potential for the reverse reaction i.e. for S0 to S2- which is -0.28.
So for this reaction----------
H2S + Fumarate
S0 + Succinate
In the above reaction S2- changes to S0
The reduction potential is +0.28.
