Effect of temperature on the heat of combustion

[kester]

Like in a topic. I just got this question and I am looking for some help.

I found this one http://wikieducator.org/The1stLawofThermodynamicsLesson5 I don't know, is the heat of combustion is the same as entalphy?

Heat of combustion is defined at standard conditions. So there is no effect of temperature.

Standard (my addt'n & emphasis) Heat of combustion is defined at standard conditions.

Heats of reactions/combustions at other conditions are functions of T,P.

Heat of combustion is the difference in enthalpy between the products of the reaction and the reactants at a specified temperature and pressure. It refers to reactants in molar stoichiometric proportions producing products in stoichiometric molar proportions.
