Chloroform, CHCl 3 , is formed from methane and chlorine in the following reaction. Calculate r

Question:

Chloroform, CHCl₃, is formed from methane and chlorine in the following reaction.

Calculate ∆_rH°, the enthalpy change for this reaction, using the enthalpies of formation of CO₂(g), H₂O(ℓ), and CHCl₃(g) (∆_fH° = −103.1 kJ/mol), and the enthalpy changes for the following reactions: CH4(g) + 2 O(g) 2 HO(l) + CO(g) A,H-890.4 kJ/mol-rxn 2 HCl(g) H(g) + Cl(g) A,H = +184.6 kJ/mol-rxn
