Cesside the aqueous reactions

$A+B{R}_{\text{d}\text{e}\text{n}\text{i}\text{r}\text{e}\text{d}},r_R=1\mathrm{.}0C_A^{15}{C}_R^{03}$

$A+B{S}_{\text{u}\text{n}\text{u}\text{r}\text{a}\text{r}\text{e}\text{t}\text{e}\text{d}},r_5=1\mathrm{.}0C_A^{0\mathrm{.}5}{C}_g^{1\mathrm{.}8}$

For $80\%$ couversion of $A,$ find the concentration of $R$ in the product stream. Equal volumetric fow rates of the A asd of $B$ streams are fed to the reactor, and each stream has a concentratica of $50$ mol$/$liter of reactant.

The flow in the reactor follows.

$($a$)$ plug nlow.

$($b$)$ mised flow, and

the bent of the for plug$-$mixed contpeting schemes
