The volume of a tubular reactor is determined with the plug$-$flow assumption by taking the fractional conversion as $0\mathrm{.}9.$ The reaction taking place in this resclor is first order. In a separate experiment, the value of the axial Peclet number is also determined.

a$)$ Do you expect to achicve the fractional conversion value of $0\mathrm{.}9$ if$,$

$\frac{U_{0}L}{D_2}=100$;$\frac{U_{0}L}{D_2}=5$;$\frac{U_{0}L}{D_z}=0\mathrm{.}1$

b$)$ Discuss whether one would expect to achieve lower, higher, or equal tractional comersion in each case, without evaluating the bumerical values of fractional eonversion.

c$)$ Evaluate the fractional conversion of reactant A for the case of $\frac{E_{4}1}{D_x}=5.$
