5. Hydrogen cyanide is a highly poisonous, volatile liquid. One way in which it can be prepared is by the reaction: CH4 (g) + NH3 (g)→ HCN (g) + 3 H2 (g) Use Hess' law and the following thermochemical equations to find the heat of the above reaction at constant pressure. N2 (g) + 3 H2 (g) → 2 NH3 (g); AH =-91,8 kJ C (graphite) + 2 H2 (g) → CH4 (g); AH =-74,9 kJ H2 (g) + 2 C (graphite) + N2 (g) → 2 HCN (g); AH = 270,3 kJ [4] %3D
