Questlon $2$: MULTTPLE REACTIONS $(31$ Marks$)$

$2\mathrm{.}1$ A CSTR is operated at steady state. Its space time $($r$)$ is $1250s.$ The following chemical reections take place in it:

$2AB+C,r_c=k_1{C}_A^2$

$A+B2D,r_0=2k_2{C}_A{C}_n$

The following concentrations are known:

$\backslash$table$[[,$A$,$B$,$C$,$D$],[$Inlet $($mol$/$L$),2\mathrm{.}50,0,0,0],[$Outlet $($mol$/$L$),0\mathrm{.}45,,0\mathrm{.}75,]]$

$2\mathrm{.}1\mathrm{.}1$ Calculate the outiet concentrations of $B$ and $D.$

$(6)$

$2\mathrm{.}1\mathrm{.}2$ Calculate $k_1$ and $k_2.$

$(10)$

$16$

$2\mathrm{.}2$ For the following set of reactions, the rates are in mol$/$L$.$min and the concentrations are in $mo\frac{l}{L}$ :

$(1)A+BD,-r_{1A}=800e^{(-8000T_K)}{C}_A^{0\mathrm{.}5}{C}_B$

$(2)A+B{U}_1,-r_{2B}=10e^{(-300T_K)}{C}_A{C}_B$

$(3)D+B{U}_2,-r_{3D}={10}^6{e}^{(-8000T_K)}{C}_D{C}_B$

$2\mathrm{.}2\mathrm{.}1$ What temperature $($in the range $(S_{\frac{D}{U_1}{U}_2})C_{A0}{C}_{B0}=1mo\frac{l}{L}{v}_0=1S_{\frac{D}{U_1}{U}_2}(12)300K$
