# 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 drops to 0.1 bar (this last pressure is low enough that CHClF2 can be considered to be an ideal gas). At these operations conditions, the gas can be represented by a one-term virial equation of state: The following data are available for this gas: in cm3/mol and in J/mol.K What is the temperature of CHClF2 exiting the valve

### An experiment to measure the enthalpy change for the reaction of aqueous copper(II) sulfate, CuSO4(aq) and zinc, Zn(s) was carried out in a coffee cup calorimeter as follows. Cu2+(aq) + Zn(s) → Cu(s) + Zn2+(aq) 50.0 cm3 of 1.00 mol dm–3 copper(II) sulfate solution was placed in a polystyrene cup and its average temperature after three readings was noted to be 25OC and the zinc powder was added . The final temperature was noted to be 91.5 OC. Calulate the heat of the reaction in kJ
