1. Calculate AH for the reaction: C2H4 (9) + H2 (9)→ C2H6 (9),
from the following data.
C2H4 (9) + 3 O2 (G) → 2 CO2 (g) + 2 H2O () AH = -1411. kJ
C2H6 (g) + 3½ O2 (g) → 2 CO2 (g) + 3 H2O () AH = -1560. kJ
H2 (9) + ½ O2 (g) → H2O () AH = -285.8 kJ
2. Given the following data
203(g) → 302 (g)
AH = -427 kJ
O2(g)
20(g)
AH = 495 kJ
NO(g) + 03(9) → NO2(g) + O2 (g)
AH = -199 kJ
%3D
calculate AH for the reaction
NO(g) + 0
(g)
→ NO2 (g)
