Thermochemical equations 1, 2 and 3 were determined by experiment. 1. N₂(g) + 3 H₂(g) → 2 NH3(g) AH = -91.8 kJ 2. C(s) + 2 H₂(g) → CH₂(g) AH = -74.9 kJ 3. H₂(g) + 2 C(s) + N₂(g) → 2 HCN(g) AH = +270.3 kJ Net: CH₂(g) + NH3(g) → HCN(g) + 3 H₂(g) AH= i 11. In equation 2 the products have potential energy than the reactan and during the reaction the kinetic energy of the surroundings will The statement above is best completed by the answers in row: Row O 0 O i more less more less ii increase decrease decrease increase
