Amixture a of 17 mol%, b of 39 mol%, and c of 44 mol% is held at 480 k in a closed 30 litre vessel at 110 atm. the critical pressure of the mixture is 55 atm and the critical temperature is 400 k a. from the chart find the value of z (critical value) b. use the law of corresponding states to find the number of moles of each species in 2. the vessel. use the appropriate compressibility chart, and show your work on the chart.
