The gas phase irreversible first-order reaction A----> 3B , is carried out in PFR where the feed is equal molar in A and inerts. the conversion under these circumstances is 50%. The exit from PFR is fed to a CSTR of the same volume and carried out under identical conditions (ie temperature and pressure) in a CSTR of the same volume. What is the coversion exiting the CSTR?
