I did the same thing for part b: Flipped the E for the lesser value (Fe half reaction) 0.80 - 0.771 = 0.029, but it wasn't correct.
I'm not getting the correct answers, sorry. Can you expand on the explanations?
Here's my work, but it wasn't the correct answer: The two half-reactions: Fe3+ + e- --> Fe2+ E = 0.77 V 2H+ + 2e- --> H2 E = 0 V You multiply the first one by 2, so it looks like the formula above: 2 Fe3+(aq) + H2(g) 2 Fe2+(aq) + 2 H+(aq). Ecell = 0.77 V
