The standard enthalpy of combustion ΔH⊖c is the enthalpy change when one mole of a substance (the relative molecular mass, in grams) is completely burned in oxygen, under standard conditions. From: Newnes Engineering and Physical Science Pocket Book, 1993 ...
The reference state of an element is its most stable configuration under the above-mentioned conditions. Some examples of reference states are nitrogen in the form of gas molecules N2N2 and carbon in the form of graphite. The standard enthalpy of formation formula for a reaction is as follows:...
