ECH 146 Winter, 2008 Problem Set 5 Due 2/15/08 1. The liquid-phase reaction of shown below takes place in a batch reactor at 25 o C A + B C + D For an equal molar feed the following concentration-time data was obtained for A: C A /(mol/dm 3 ) 1.0 0.95 0.816 0.707 0.5 0.370 t/h 0 0.278 1.389 2.78 8.33 16.66 The following concentration time data was carried out for an initial C A (C A0 ) of 0.1 and C B0 of 1. C A /(mol/dm 3 ) 0.1 0.0847 0.0735 0.0526 0.0357 t/h 0 1 2 5 10 Determine the rate equation. 2. The following data were reported for a gas-phase decomposition of A at 504 o C in a constant volume batch reactor. Initially only A was present. t/s 390 777 1195 3155 8 Total pressure/mmHg 408 488 562 799 931 Assuming that the reaction A B + C + D

Unformatted text preview: is irreversible and goes to completion, determine the reaction equation. 3. The elementary liquid phase series reaction C B A k k → → 2 1 is carried out in a 500 dm3 batch reactor. The initial concentration of A is 1.6 mol/dm3. The desired product is B, and separation if the undesired product C is very difficult and costly. Because the reaction is carried out at a relatively high temperature, the reaction is easily quenched. k 1 = 0.4/h and k 2 = 0.01/h at 100 o C. Assuming that each reaction is irreversible, plot the concentrations of A, B and C as a function of time. 50 100 150 200 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 C i vs. t t, time (hour) C i , Concentration (mol/L) C A C B C C...
