A100. kmol/hr stream that is 96.0 mole% carbon tetrachloride (ccl4) and 4.0 mole% carbon disulfide (cs2) is to be produced from the bottom of a distillation column. the feed to the column is 83.0 mole% ccl4 and 17.0 mol% cs2 ,and 2.5 mol% of the ccl4 entering the column is recovered in the overhead stream leaving the top of the column. what is the mole fraction of ccl4 in the stream that is leaving the top of the distillation column?

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 :

plasma - state of matter made up of electrically charged particles
