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
