 Calculate the standard enthalpy change for the reaction below using the given heats of formation. B2O3(g) + 3COCl2(g) 2BCl3(g) + 3CO2(g)                 ΔHof of B2O3(g) = –1272.8 kJ∙mol–1                               ΔHof of BCl3(g) = –403.8 kJ∙mol–1   ΔHof of COCl2(g) = –218.8 kJ∙mol–1                                 ΔHof of CO2(g) = –393.5 kJ∙mol–1
