4 NH3(g) + 5 O2(g) ----------------> 4 NO(g) + 6 H2O(g)

Hrxn = Hproducts - Hreactants

= ( 4 x 90.25 + 6 x -241.8 ) - (4 x –46.11+0 )

= - 905.36 kJ /mol

Srxn = Sproducts - Sreactants

= (4 x 210.6 + 6 x 188.7 ) - ( 4 x 192.3 + 5 x 205)

= 180.4 J / mol K

Grxn = Gproducts - Greactants

= (4 x 86.57 + 6 x –228.6 ) - ( 4 x –16.48 + 0 )

= - 959.4 kJ / mol
