Using the equations 2 Fe (s) + 3 Cl₂ (g) → 2 FeCl3 (s) AH = -800.0 kJ/mol Si(s) + 2 Cl: (g) → SiCl4 (s) AH = -640.1 kJ/mol

Question

Using the equations
2 Fe (s) + 3 Cl₂ (g) → 2 FeCl3 (s) AH = -800.0 kJ/mol
Si(s) + 2 Cl: (g) → SiCl4 (s) AH = -640.1 kJ/mol
Determine the molar enthalpy (in kJ/mol) for the reaction
3 SiCl (s) + 4 Fe (s)→ 4 FeCl3 (s) + 3 Si (s)
