Consider the liquid phase reaction

which is to take place in a PFR$.$ The following data was obtained in a batch reactor.

$\backslash$table$[[x,0,0\mathrm{.}4,0\mathrm{.}8],[-ra(mo\frac{l}{d}{m}^3*s),0\mathrm{.}01,0\mathrm{.}008,0\mathrm{.}002]]$

If the molar feed of A to the PFR is $2mo\frac{l}{s},$ what PFR volume is necessary to achieve $80\%$ conversion under identical conditions as those under which the batch data was obtained?
