Product description
- Find the thermal effect of a reaction
CH4 Cl2 = CH3Cl HCl,
if the thermal effects of such reactions are known:
CH4 2O2 \u003d CO2 2H2O (l) ΔrH \u003d -212790 cal
CH3Cl 3 / 2O2 \u003d CO2 HCl 2H2O (l) ΔrH \u003d -164000 cal
H2 1/2O2 = H2O(l) ΔrH=-68317 cal
1/2H2 1/2Cl2 = HCl ΔrH=-22060 cal
