Solution: From the enthalpies of reactionH2 (g) + F2 (g) → 2 HF (g) ΔH = -537 kJC (s) + 2 F2 (g) → CF4 (g) ΔH = -680 kJ2 C (s) + 2 H2 (g) → C2H4 (g) ΔH = +52.3 kJcalculate ΔH for the react

From the enthalpies of reaction

H_{2} (g) + F_{2} (g) → 2 HF (g) ΔH = -537 kJ

C (s) + 2 F_{2} (g) → CF_{4} (g) ΔH = -680 kJ

2 C (s) + 2 H_{2} (g) → C_{2}H_{4} (g) ΔH = +52.3 kJ

calculate ΔH for the reaction of ethylene with F _{2}:

C_{2}H_{4} (g) + 6 F_{2} (g) → 2 CF_{4} (g) + 4 HF (g)
