POST CODE AND PLOTS

Use matlab or polmyath post code and plot !!!!

The following two liquid phase reactions A + B --> D (desired product) A + B --> U (undesired product) are carried out in a perfectly insulated CSTR. The desired reaction is first order in A and zero order in B, while the undesired reaction is zero order in A and first order in B. Inlet: Species B enters at an inlet temperature of 50C. CBinlet = 1 mol/dm3. The molar flow rate of B entering the reactor is 10 mol/min. No A is coming in the inlet. Initial: Species A and B are initially in the reactor at a temperature of 50C. The initial value of liquid V is 100 dm3. CAinitial = 5 mol/dm3. CBinitial = 1.2 mol/dm3. The following data apply (neglect temperature dependence of the heat capacities and heats of reaction): CpA = 20 cal/mol*K ; CpB = 30 cal/mol*K ; CpD = 50 cal/mol*K ; CpU = 40 cal/mol*K For reaction 1 the heat of reaction at the operating temperature is: -3000 cal/mol of A For reaction 2 the heat of reaction at the operating temperature is: -5000 cal/mol of A k1 = 10exp(-2000/T) min-1 ; (T in Kelvin) k2 = 20exp(-3000/T) min-1 ; (T in Kelvin) Plot selectivity as a function of time + concentrations and temperature
