Hess’s Law b) Calculate the ∆H for the reaction:
Ti(s) + 2Cl2 (g) → TiCl4 (l)
Using the following chemical equations and their respective enthalpy changes:
Ti(s) + 2Cl2 (g) → TiCl4 (g) ∆H = -763 kJ TiCl4 (l) → TiCl4 (g) ∆H = 41 kJ
b) Calculate the ∆H for the reaction:
2CO(g) + O2 (g) → 2CO2 (g)
Using the following chemical equations and their respective enthalpy changes:
2C(s) + O2 (g) → 2CO(g) ∆H = -221.0 kJ C(s) + O2 (g) → CO2(g) ∆H = -393.5 kJ
