Reactor Design

Consider an irreversible, liquid-phase, elementary reaction 2A ⟶ B taking place in two continuous stirred tank reactors (CSTRs) in series under the same temperature. The second CSTR is two times larger than the first reactor by volume. The intermediate conversion of A exiting the first reactor prior to entering the second reactor is 50%.

What is the value of the Damköhler number for the first reactor

What is the conversion of A exiting the second CSTR? 

If a plug flow reactor (PFR) with a volume two times larger than the first CSTR is 
used as the second reactor instead, what would the conversion of A exiting the PFR?
