Ireversible reaction $2PR$ is a $2$nd order reaction. $P$ conversion $=30\%$ & $60\%,$ volumetris rate $P=2\mathrm{.}5$ lt$/$men $,P$ concentration in feed $=3$mol$/$lt$.$

a$.$Calculate the reactor valume if a Pipe Flow Reactor $($RAP$),$ is used.

b$.$ Calculate the reactor volume if a Pipe Flow Reactor $($RATB$)$ is used.
