In a continuous manufacturing process, chlorodifluoromethane (CHClF₂) initially at 10 bar and 420 K, passes through an adiabatic pressure reducing valve so that its pressure is 0.1 bar (this last pressure is low enough that CHClF₂ can be considered to be an ideal gas). At these operating conditions, the gas can be represented by a one-term virial equation of state:

B(T) V PV RT The following data are available for this gas: 256, 100 cm T mol' B(T) = 297.6- and the ideal

What is the temperature of the chlorodifluoromethane exiting valve? How much entropy is generated in the process per mole of chlorodifluoromethane that flows through the valve?

B(T) V PV RT The following data are available for this gas: 256, 100 cm T mol' B(T) = 297.6- and the ideal gas heat capacity is Cp = J 0.093T- mol. K = 27.93 +
