| Popis: | The temperature dependences of the heat capacities C°p,m for 1-1 complexes of dimethyl-cadmium with dimethylselenium and of dimethylcadmium with dimethyltellurium have been studied at temperatures from 5 K to 310 K in a vacuum adiabatic calorimetric cryostat within 0.2 per cent. Temperatures and enthalpies of melting for the complexes have been determined. From the values obtained the thermodynamic functions: ΔT0H°m, ΔT0S°m, and O°m, have been calculated over the temperature range from T = 0 to 310 K, and the thermodynamic quantities for the processes: ( CH 3 ) 2 Cd ( l ) + ( CH 3 ) 2 ( Se ) ( l ) = ( CH 3 ) 2 Cd ⋅ Se ( CH 3 ) 2 ( l ) , and ( CH 3 ) 2 Cd ( l ) + ( CH 3 ) 2 ( Te ) ( l ) = ( CH 3 ) 2 Cd ⋅ Te ( CH 3 ) 2 ( l ) have been estimated also at T = 298.15 K and p = 101.325 kPa. |
