Deltar195.kJ/molTD-HFCAdedeji, Connor, et al., 1978The value for the reaction enthalpy corresponds to the thermal decomposition experiments and leads to -415. kJ/mol for the enthalpy of formation of W(CO)3(MeCN)3(cr). The value -405.0±12.0 was recommended by the authors Adedeji, Connor, et al., 1978

C9H9N3O3W (cr) + 3Carbon monoxide (g) = Tungsten hexacarbonyl (g) + 3Acetonitrile (g)

By formula: C9H9N3O3W (cr) + 3CO (g) = C6O6W (g) + 3C2H3N (g)
