Problem:

The elementary irreversible gas phase reaction $2$A $->$ B is carried out isothermally with no pressure drop in a PFR$.$

Given:

$y_{Ao}=1$

$P_O=8\mathrm{.}2$atm

$T_O=227C$

$v_O=25\frac{d{m}^3}{(s)}$

$k=10\frac{d{m}^3}{(mol)*s}$

Use measures other than conversion to plot molar flow rates of A and $B$ down the reactor.
