$5$ An aqueous feed to a continuously stirred tank reactor $($CSTR$)$ which has a reactor

volume of $180$ liter, consists of $0\mathrm{.}4mo\frac{l}{?}$ liter of A and the same molar concentration of $F.$

The feed rate is $3\mathrm{.}0$lite$\frac{r}{m}in.$

The desired product $B$ is formed by different reactions as shown below.

If the reactor is operated at the temperature $T_1$ with the rate constants as shown below,

i$.$ what are the values of $C_A,C_B,C_U$ and $C_F$ at the reactor exit?

ii$.$ what is the yield of $B($based on the feed A and $F$ combined$)?$

At another temperature $T_2,$ the rates $r_3$ and $r_s$ are both negligible. Then,

iii. is the CSTR or PFR preferred or is there any preference? Show your calculations?

Other information

At the temperature $T_l,$

$k_1=0\mathrm{.}01mi{n}^{-1}$

$k_2=0\mathrm{.}02mi{n}^{-1}$

$k_3=0\mathrm{.}03mi{n}^{-1}$

$k_4=0\mathrm{.}50\frac{L}{g}$mol$-$min

$Cj$ is the concentration of species $j$

PFR is plug flow reactor.
