Question:

Consider the R-245fa (1) + n-pentane (2) system in Figure 13-13. At the different state points (black dots) provided on Figure 13-13, name the equilibrium phases and the compositions of those equilibrium phases. Note that the overall mixture composition is given using the symbol w. 

Point A: T = 245 K; P = 0.1 bar; w1 = 0.2  

Point B: T = 220 K; P = 0.1 bar; w1 = 0.3 

Point C: T = 228 K; P = 0.1 bar; w1 = 0.97 

Point D: T = 234 K; P = 0.1 bar; w1 = 0.5 

Point E: T = 260 K; P = 0.1 bar; w1 = 0.6

Figure 13-13 

T(K) 320 300 280 260 240 220 200 0 A 0.2 B D E 1 bar 0.1 bar 0.4 0.6 Mole fraction R-245fa 0.8 Co 1
