Question

b. For the mixing process of ideal gases, the molar change in entropy is =-REX, In X, AS mix where Xi is the molar fraction of each gas. For each mix of three gases (A B, and C) calculate ASmiting for the following six compositions: п III XA 0.7 ХВ - 0.2 IV VI XA 0.9 XA 0.6 XA 0.33 ХВ - 0.33 XA 0.8 XA 0.5 XB 0.001 XB 0.15 XB 0.3 XB 0.3 ХC - 0.1 ASmir XC 0.009 XC 0.05 XC 0.1 XC 0.2 XC 0.33 ASi ASmi ASmi ASmi ASm

This is a Physical Chemistry problem, the table must be completed. Thank you in advance!

Al meeR [ 0.9.6(0.9)+ 0.014, (0.001) en (0.9)+ 0.001 (0.001) +0.009 en 10.000 =-R[-0.95 - 0.007 -0.0427 - R ③ Donii = -R [ 0.14 0.B + 0.15 in (0.15) + 0.05 M 10.05]] - -R -0.178 -0.284 -0.15] = 0.61R (II Asmie = -RC 0.76.10.7) + 0.2M(0.2) +0,1n (0.1) =-R [-0.25 -0.32 0.23] = 0.8R

Asmisi = - R50.600.6 + 0.34 0.3 +0.1 (0.1) = -R [ -306 - 0.361 - 0-23] = 0.89 R ( Donir- – Ro.shost 0.35 0.3 + 0.21 0.2 - -R [0.346 – 0.361 -0.3217 1.02R KT Asmies -R [0.33 47(0.13) + 0.33 60-32) +0.33 40(0.33)] - -R [~0.365-0.365 0.365] = 1.09R
