Title: Effect of concentration of alcohol on heat of combustion?
Post by: abbey.s.gibson on April 18, 2018, 09:42:53 am

Hey guys,

I was wondering whether anyone could help me answer a question for my EEI poster. I am investigating the effect of concentration of methanol, ethanol and propanol on their enthalpy of combustion. What background information is there to back up why the higher conentrations gave off more heat? I'm not sure what to do to back this up. Can anyone help?
Thanks everyone.

Consider the substance that the rest of the solution is made of :)

Hehe. I will provide a further hint:

Aqueous Solution.

This is related to why black coal is a more efficient in coal-fired power stations than brown coal...
