Homework Help: Hydrocarbon enthalpy profiles

  1. Jan 22, 2008 #1
    Hi i am a IB student currently working on my extended essay in the field of chemistry and was wondering if any one could suggest where i could find the enthalpy profiles for specific hydrocarbons including standard enthalpy changes for fuels such as: petroleum, diesel, ethanol, methanol, bio-diesel and any other fuels that i might be able to find literature values for.

    the premis of the experiment is to examine how the fuel to air mixtures affect the power of the combustions and which fuels have the most violent explosions. What i need the the enthalpy profiles for is to examine the bi-products of combusting these fuels.

    If i could get any suggestions it would be much appreciated because the only values i have currently are those recorded by other students and i would like my sources to have less error in them in order to compare my results to accurate literature vales.

    any help would be much appreciated,

    Here is an excellent government reference that should get you started

    http://webbook.nist.gov/chemistry.html [Broken]

    search by name and click on thermochemistry data links.

    As for the fuels like gasoline and diesel I was lazy and used wiki


    I'm not sure how reliable the sources are for the enthalpies of combustion for the fuels, but you can look up the source and determine for yourself.

    thanks for the help

    I was just wondering if any one currently using this forum has done any enperimenting or knows of any experiments where the emission gasses of proposed alternative fules has been studies for example CO2 levels and NOx emissions has been studied. If you have please give me the heads up on them i would find them especially useful when making conclusions to my findings.
