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?

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

the maximum mass of nh3 is nh3 in grams
