The standard heats of formation of H20(g), H2S(g), H2Se(g). and H2Te(g) are -241.8. -20.17, +29.7, and +99.6 kJ/ mol. respectively. The enthalpies necessary to convert the elements in their standard states to one mole of gaseous atoms are 248. 277. 227, and 197 kJ/mol of atoms for O. S. Se. and Te. respectively. The enthalpy for dissociation of H2 is 436 kJ/mol. Calculate the average H—O. H—S. H—Se. and H—Te bond enthalpies, and comment on their trend.
