3. (25 points) A reactor with multiple input streams is shown in the figure. The reaction is A+B. The linearized component A mole balance equation is: TCA(1) + Ca(1)-KCASCAD(1) + KroFt) + KrF(t) The parameters have the following values: Tp 10 minutes CAD(t), Fo(1) CAI, FI(1) KC-0.5 (no units) ] [ Kro3 mole A-minute/(Liter) Kr=2 mole A-minute/(Liter) CA(1-0)- 1 mole/Liter A B CA2(1),F2(t) At time t-0, the following changes occur simultaneously: a step change decrease in CAD(1) occurs so that ACAB-2 moles A/Liter a step change increase in Fi(t) occurs so that AF+2 L/minute. a. Calculate the final exit concentration Ca(t) that will be achieved at very long times after the disturbances occur. b. Estimate the time at which 95% of the change in the exit concentration Ca(t) has occurred. 3. (25 points) A reactor with multiple input streams is shown in the figure. The reaction is AB.
