Standard enthalpy of reaction table
WebbThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H. 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data.
