An isothermal steady state mixed flow reactor (CSTR) of 
volume is used to carry out the first order liquid-phase reaction A → products. Fresh feed at a volumetric flow rate of Q containing reactant A at a concentration 
mixes with the recycle stream at a volumetric flow rate RQ as shown in the figure below.
It is observed that when the recycle ratio 
, the exit conversion 
. When the recycle ratio is increased to 
, the new exit conversion (in percent) will be:
