Hi Honi Mai, I'd be happy to answer this question for you,
Would you be able to check something for me however, as the enthalpy of formation of CO2 should be a very negative value. Should it be -393.4 kJ/mol?
Can you check the values you have been given and I'll calculate the answer for you if you would like.
Many thanks for your question,
Ok, give me a few minutes and I'll calculate the answer.
Hi Honi Mai,
I've finished the answer, I've written it out as I think it is easier than trying to put all the formulae into typed format.
I can attach the image and send it to you on Just Answer, is this ok?
Thanks for accepting, look out for the decimal points as they're a little faint, but you should still be able to see them. Also, just wondering, is the enthalpy of formation for C5H12 +35.1 kJ/mol or -35.1 kJ/mol?
Ok, Have to change the answer slightly. One second.
Just need to change H1 to -35.1 kJ/mol.
H2 at the bottom is simply -3417.8 + 35.1 = 3382.7 kJ/mol
Hopefully it should all work out now. Let me know if you have any problems following the answer.
Thank you again for your question,
