Explanation Write the critical temperature of gas mixture. T c = y 1 T c 1 + y 2 T c 2 (I) Here, the mole fraction of nitrogen is y 1 , the mole fraction of argon is y 2 , the critical temperature of nitrogen is T C1 , and the critical temperature of argon is T C2 . Substitute 126 K for T c 1 , 0.5 for y 1 , and 151 K for T c 2 in Equation (I). T c = ( 0.5 ) ( 126 ) + ( 0.5 ) ( 151 ) = 138.5 Write the critical pressure of gas mixture ( p c ) . p c = y 1 p c 1 + y 2 p c 2 (II) Here, the critical pressure of nitrogen is p c 1 and the critical pressure of argon is p c 2 . Calculate reduced temperature for the mixture ( T R ) . T R = T T c (III) Calculate reduced pressure for the mixture ( p R ) . p R = p p c (IV) Write the volume of the tank. v = Z n R − T P (V) Here, compressibility is Z , total number of moles is n , universal gas constant is R − , temperature is T , and pressure is P . Conclusion: Refer table A-1, “Critical properties of selected elements and compounds”, obtain the critical temperature and pressure for nitrogen as 126 K and 33.9 b a r . Refer table A-1, “Critical properties of selected elements and compounds”, obtain the critical temperature and pressure for argon as 151 K and 48.6 b a r . Calculate the mole fraction value of nitrogen. y 1 = 50 100 = 0
