$5.$ Adiahatic PFR $(10$ points$)$

The following reaction oscurs in an afiabatic PFR:

$A(g)R(g),-r_A={}_0{e}^{-1F_A}{C}_A$

${}_0=1\mathrm{.}0mi{n}^{-1},E=1000ca\frac{l}{m}$ole,$x_4=600K,H_c=-500ca\frac{l}{m}$ole.

$C_p=5ca\frac{l}{m}$ole$-K$ for both A and $R.$ The exit coaversion $is0\mathrm{.}9.$

A$.$ What is the temperantere at the reactor exir?

$\{\begin{array}{ccc}\text{:}& [Heafort-& In]\end{array}$

Hent genated

Tont

$C_p$ Tait $-C_{p600}=x_4(-$ Arren $).$

$T_{\text{o}\text{u}\text{t}}=x_A(-t{x}_n)+600c_p$

:$.$ Tout $=690K$

B$.$ Whas is the ratio of raction nate at the reactore entrance to that for the reactor exit?

Part A is correct but rhthe answer to B is $9$ and I cant get the right answer.
