Product description
3. Calculate the change in entropy when 1.3 mol of HBr substance is heated from temperature T1= 170 K to T2 = 220 K at Р= 1.013 I05 Pa, if known: Тmelt = 184 K, Тboil = 206 K, molar heat of fusion Δ Нmelt = 2.41 kJ /mol and molar heat of vaporization ΔNsp =17.68 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 = 14.28 J/mol*K, Срж = 28.56 J/mol*K.
