DE-AC02-06CH11357. 1, 2] enthalpy of formation based on version 1.122 of the Thermochemical Network This version of ATcT results was partially described in Ruscic et al. The enthalpy of formation of ammonia when calculated from the following bond energy data is (B.E of N - H, H - H, N ≡ N is 3 8 9 k J m o l − 1, 4 3 5 k J m o l − 1, 9 4 5.

These tables include heat of formation data gathered from a variety of sources, including the primary and secondary literature, as well as the NIST Chemistry WebBook. You need to know the values of the heat of formation to calculate enthalpy, as well as for other thermochemistry problems. Your IP: 45.123.144.16 Note that the table for Alkanes contains Δ f H o values in kcal/mol (1 kcal/mol = 4.184 kJ/mol), and the table for Miscellaneous Compounds and Elements contains these values in kJ/mol.
