For part b, I don't want to seem stupid, but are you sure that's the method for fuel cells? Because it seems like you're still talking about combustion engines.

So the energy release is -702.36 kJ and 20% of that would be -140.47 kJ which would be the work done? Also, I haven't really a clue how to start b even after the hint you gave me... I don't know how to find the combustion temp of methanol. I'm sorry for all the questions, but I really am lost...

Homework Statement An internal combustion engine operated with methanol (CH3OH) as the fuel has a thermodynamic efficiency of 20%. a) How much work is derived from burning one mole of ethanol in the engine? b) What is the max work that could be derived by reacting the methanol with pure...
