The gas phase irreversible first-order reaction

is carried out first in a PFR, where the feed is equal molar in A and inerts. The conversion under these circumstances is 60%. The exit from the PFR is fed to a CSTR of the same volume and carried out under identical conditions (i.e., temperature, pressure) in a CSTR of the same volume. What is the conversion exiting the CSTR?
