Problem 4-25 (Level 2) The reversible, liquid-phase isomer- ization reaction A ER is first order in both directions. The equilibrium constant based on concentration for the reaction as written is 2.0 at temperature T1. An ideal CSTR with a volume of 10001 is being operated at T. The molar flow rate of A to the CSTR is 1500 mol/min. The concentration of A in the feed is 2.5 mol/l; there is no R in the feed. 1. What is the lowest possible outlet concentration of A that can be obtained at T, for a feed containing 2.5 mol/l of A and no R? 2. The actual concentration of A leaving the CSTR is 1.5 mol/l. What is the value of the forward rate constant at Ti? 3. A second CSTR with a volume of 1000 1 is added in series with the first. The molar flow rate of A to the first reactor is increased so that the concentration of A leaving the second CSTR is 1.5 mol/1. The feed composition is unchanged. What is the new flow rate of A to the first reactor? 1 5
