    This is a comparison between two experiments.

    If, for instance, a student lets the burner carry on longer than in the previous experiment and extinguishes it later, with a greater temperature rise compared to the first experiment why would there still be a similar value of enthalpy change of combustion be calculated?

    Surely a greater number of moles being burnt would mean the enthalpy change figure would be less exothermic?

    I'd appreciate if someone could clear this up for me, just a little confused. :confused:

    Enthalpy is measured PER MOLE ...
