Question
Using two or more of the following,
N2(g) + 3/2 O2(g) N2O3(g), AH° = 83.7 kJ;
N2(g) + O2(g) – 2NO(g), AH° = 180.4 kJ;
1/2 N2(g) + O2(g) NO2(g), AH° = 33.2 kJ;
1/2 N2(g) + 3/2 H2(g) NH3(g), AH° = -45.9 kJ,
determine AH for the following reaction. NO(g) + NO2(g) N203(g)
a.-39.7 kJ
O b. 207.1 kJ
O c. 39.7 kJ
O d. -207.1 kJ
O e. 24.3 kJ
