Question

1. Given the following data: C2H2(g) + 5/2 O2(g) ---> 2CO2(g) + H2O(l) ?H = -1300 kJ C(s) + O2(g) ---> CO2(g) ?H = -394 kJ H2(g) + 1/2 O2(g) ---> H2O(l) ?H = -286 kJ Calculate ?H for the reaction: NO(g) + O(g) ---> NO2(g)

          1. Given the following data:

C2H2(g) + 5/2 O2(g) ---> 2CO2(g) + H2O(l)   ?H = -1300 kJ
C(s) + O2(g) ---> CO2(g)   ?H = -394 kJ
H2(g) + 1/2 O2(g) ---> H2O(l)   ?H = -286 kJ

Calculate ?H for the reaction: NO(g) + O(g) ---> NO2(g)
