H2 h value
WebΔHo rxn = ΣnpΔH o p – ΣnrΔH o r where np and nr are the stoichiometric coefficients of each of the products and each of the reactants, respectively. For example, for a reaction aA + bB → cC + dD, we would have ΔHo rxn = [cΔH … Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively.
