Chloromethane, , is formed from methane and chlorine in the following reaction:

 
Chloromethane, CH3CI, is formed from methane and chlorine in the following reaction:
CH4 (g) + Cl2 (g) → HCl(g) + CH3 Cl(g)
Calculate A, H, the enthalpy change for this reaction, using the enthalpies of formation of CO2 (g), H2O((), and
CH,CI(g), (A,H =-83.68 kJ/mol), and the enthalpy changes for the following reactions:
CH4 (g) +2 02 (g) → 2 H2O(() + CO2(g)
A,H"
= -890.4 kJ/mol-rxn
2 HCl(g) → H2 (g) + Cl2 (g)
