A still is charged with 1000 moles of a binary mixture that is 82.0 mole% cyclohexane (more volatile) component A and 18.0 mole % Toluene (less volatile) component B. This mixture is distilled until 163 moles remain in the still and the cumulative distillate is collected. You may assume that the relative volatility (aLight-Heavy 2.45) remains constant during the distillation process and equilibrium data and an initial analysis of the Rayleigh equation is provided in the table provided. wyp el dia de 700.3 782.8 805 121.9 112 1992 1 to 12134 12458 298.8 308.9 3192 329.7 FREE 3406 FISE 11214 11587 486.1 11824 424.9 4382 4318 853.7 872.1 16.728 9020 31.2 1334 6.71 9.37 3749 9215 953.3 3870 300.3 194 9600 1007 2 4119 1994 1014 ww FIR Template Component THE ca 20 75 81.31 1918 HA TE CH M www * 91.29 1000 1000 TH A IMO 1540 19601060 IMO OM) 0.830 0.919 (640 kix 2008 BETIN -BOT-2 500. 3212 LAVE www. 10304 Wel 1/lyA*Avg(10) Summation 1.M 10.110 201 $135 WATE 10014 8.381 327 0349 4 393 390 BRAKAD ENSIM 4441 4654 CAF 0.417 6633318 MIL 0344 KIML 9.45 0356 0544 KNITW 1811 0977 03335 1310 www 0111 0163 6.134 0140 0.145 10.10 53140 6.140 6.306 9310 9.25 930 S YOU SAVA 3197 0316 0.704 0.976 1.318 1434 100 1022.1 1:00 11 LPH 2346 180 1449 1364 2.716 2477 3.017
