THIS IS A CHEMICAL REACTION ENGINEERING QUESTION PLS I NEED AN EXPERT WITH REGARDS TO THIS FIELD THANKS $!$

follows an elementary rate law and takes place in a $1-m^3$ CSTR$,$ to whi volumetric flow rate is $0\mathrm{.}5\frac{m^3}{m}in$ and the entering concentration of $A$ is The reaction takes place isothermally at $300K.$ For an equal molar fi A and $B,$ the conversion is $20\%.$ When the reaction is carried out adi cally, the exit temperature is $350K$ and the conversion is $40\%.$ The heat i ities of A$,$ B$,$ and C are $25,35,$ and $60k\frac{J}{m}ol*K,$ respectively. It is pre

to add a second reactor of the same size downstream in series with the first CSTR$.$ There is a heat exchanger attached to the second CSTR with $UA=4\mathrm{.}0k\frac{J}{m}in*K.$ and the coolant fluid enters and exits this reactor at virtually the same temperature the coolant feed enters $350K.$

$($a$)$ What is the rate of heat removal necessary for isothermal operation?

$($b$)$ What is the conversion exiting the second reactor?

$($c$)$ What would be the conversion if the second CSTR were replaced with a $1-m^3$ PFR with $Ua=10k\frac{J}{m^3}*min$ and $T_a=300K?$

$($d$)$ A chemist suggests that at temperatures above $380K$ the reverse reaction cannot be neglected. From thermodynamics, we know that at $350K.K_c=2d\frac{m^3}{m}ol.$ What conversion can be achieved if the entering temperature to the PFR in part $($b$)$ is $350K?$

$($f$)$ Repeat part $($c$)$ assuming the reaction takes place entirely in the gas phase $($same constants for reaction$)$ with $C_{70}=0\mathrm{.}2mo\frac{l}{d}{m}^3.$
