The gas phase reaction $AB+C$ follows an elementary rate law and is to be carried out first in a PFR and then in a separate experiment in a CSTR$.$ When pure A is fed to a $10L$ PFR at $300K$ and a volumetric flow rate of $5\frac{L}{s},$ the conversion is $80\%.$ If the mixture of $50\%$A and $50\%$ inert $($I$)$ is fed to a CSTR at $300K$ with a volumetric flow rate of $5\frac{L}{s},$ what size of CSTR should be used to have the same conversion as PFR$?$
