There are two CSTR reactors in series, the first one is half full of water with component A with concentration of CA1 and the second reactor is half full of pure water. At initial time, a stream with volumetric flow rate of (E +1) X 9 and concentration of CAO enters to the first reactor. The output of the first reactor is closed. After fulling the first reactor, the output becomes open and a stream with volumetric flow rate of (E+1) 9 enters to the second reactor. The output of the second reactor is also (E+1) 9. ---Calculate CA in the first reactor before and after fulling. ----Calculate CA in the second reactor
