###### Question:

1. Calculate AH for the reaction C2H4 (8) + H2() → C2H6), from the following data. C2H4 (g) + 3 02 (®) → 2 CO2 (s) + 2 H20 (1) C2H6 (g) + 7/2 02(g) → 2 CO2(g) + 3 H20 (1) H2 + 1/2O2() → H20 (1) AH = -1411. kJ/mole AH = -1560. kJ/mole AH = -285.8 kJ/mole
2. Calculate AH for the reaction 4 NH3(g) +502 (g) → 4 NO(g) + 6 H20 (g), from the following data. N2(g) + O2(g) → 2 NO(g) N2 () + 3 H2 → 2 NH3 ( H2(g) + O2() → 2 H2O() AH=-180.5 kJ AH = -91.8 kJ 2 AH = -483.6 kJ
