Product description
Calculate the change in entropy when 1.2 mol of PCl3 is heated from temperature T1= 150 K to T2 = 360 K at Р= 1.013 I05 Pa. if known: Тmelt = 172 K, Тboil = 348 K, molar heat of fusion Δ Нmelt = 1.7 kJ/mol and molar heat of vaporization Δ Nisp = 30.66 kJ/mol. The dependence of heat capacity on temperature for the gaseous state Ср = а ВТ с'/Т2 is taken from the reference book, Сртв = 32.2 J/mol*K, Срж = 66.4 J/mol*K.
