CHEMISTRY 2001 extra credit NAME PROBLEM SET #14A: Heat of Formation DATE PERIOD 1. Calculate the heat change, DH, for the formation of nitrogen monoxide from its elements. N 2 ( g ) + O 2 ( g ) 2 NO ( g ) Use these thermochemical equations. 4 NH 3 ( g ) + 3 O 2 ( g ) 2 N 2 ( g ) + 6 H 2 O ( l ) H rxn = –1530 kJ 4 NH 3 ( g ) + 5 O 2 ( g ) 4 NO ( g ) + 6 H 2 O ( l ) H rxn = –1170 kJ (2-6) Using the table of standard heats of formation in Appendix A of your textbook, calculate the change
