A well-mixed stirred tank reactor has a volume of 200 L. The feed to the reactor is a stream with a flow rate of 50 L/min that has a concentration of species A equal to 5 moles/L. This species undergoes a reaction in the tank of the form

A ----> B

The rate of the reaction (rate of consumption of A) is given by rA=kCa with K = 4 min-1. The exit stream from the reactor is also 50 L/min assume all solutions have the same density.

a. What is the steady state concentration of A in the exit stream?

b. After the steady state is reached, if at some time the inlet concentration of A is changed to 4 moles/L, derive the resultant exit concentration of A as a function of time and find out the time elapsed for the tank to reach again steady state.

A well mixed 10m3 closed mixing tank at 18C is used to dilute 100kg/min of a 2.0% by mass NaClO3 solution to a 0.60% solution by adding water. Part 1) What is the mass flowrate of water into the tank needed at steady-state to accomplish this dilution? Part 2) You notice that some gas bubbles appear in the effluent, and after some additional literature reading, hypothesize that NaCl3 is decomposing to NaCl and O2 inside the tank because of impurities...
