$($d$)$ What is the conversion of $A$ in the first reactor?

$($e$)$ If $99\%$ conversion of $A$ is desired, what reaction scheme and reactor

sizes should you use to maximize $S_{\frac{B}{x}Y}?$

$($f$)$ Suppose that $E_1=20,000ca\frac{l}{m}ol,E_2=10,000ca\frac{l}{m}ol,$ and $E_3=30,000$

$ca\frac{l}{m}ol.$ What temperature would you recommend for a single CSTR with

a space time of $10$min and an entering concentration of $A$ of $0\mathrm{.}1mo\frac{l}{d}{m}^3?$

$($g$)$ If you could vary the pressure between $1$ and $100$atm, what pressure

would you choose?
