3. (25 points) A reactor with multiple input streams is shown in the figure. The reaction is AB. The linearized component A mole balance equation is: TCA2 (t) + Ca(t)-KCASCA'(t) + KroFo(t) + KriFi(t) The parameters have the following values: T, 10 minutes CAD(t), Fo(t) Cai, Fi(t) KCAD=-0.5 (no units) Ke-3 mole A-minute/(Liter) Kr=2 mole A-minute/(Liter) A B CA2(1),F2(1) CAZ(1-0) = 1 mole/Liter At time t= 0, the following changes occur simultaneously: a step change decrease in Co(t) occurs so that ACAD=-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(to) 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
