    How Much Work Can Methanol Fuel Generate in Different Energy Systems?

    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.

    How Much Work Can Methanol Fuel Generate in Different Energy Systems?

    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...

    How Much Work Can Methanol Fuel Generate in Different Energy Systems?

    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...
