Task 3.2. Calculate the standard enthalpy of reaction of some thermochemical equations governed by Hess Law. Direction: Solve the following items. Show complete solution. Express all standard enthalpy to kilojoules. 1. Calculate AH for the reaction 4 NH3(g) + 5 O2 (g) →4 NO(g) + 6 H₂O (g), from the following data. N2 (g) + O2(g) → 2 NO(g) N2 (g) + 3 H2(g) → 2 NH3(g) 2 H2(g) + O2(g) → 2 H₂O(g) ΔΗ = -180,5 kJ ΔΗ = .91.8 kJ ΔΗ = -483.6 kJ
