Reaction A$-->$B is known to be first order. It is going to be carried out in a CFSTR$.$

Water will run through the reactor at a flow rate, Q$,$ of $100$ m$3/$min$,$ and the volume of the CFSTR is $2000$ m$3.$

At t$=0,$ the reactant A will be added to the input stream of the reactor at an initial concentration of $100$ mg$/$L on a continuous basis.

Determine the output concentration of A as a function of time for $80$ minutes and plot reactor$-$output response curves $($CA versus time$)$ for reactant A

a$)$ if the reaction rate constant k$=0\mathrm{.}2$ min$-1$

$.$

b$)$ if the reaction rate constant k$=0\mathrm{.}4$ min$-1$

$.$

c$)$ if the reaction rate constant k$=0\mathrm{.}6$ min$-1$

$.$

All the results for part a$,$ b$,$ and c will be on the same graph. Use different colors for lines.

Also answer the following questions:

i$.$ What is the $\%$ removal efficiency of A$,$ at steady$-$state for part a$?$

ii$.$ What is the $\%$ removal efficiency of A at steady$-$state for part b$?$

iii. What is the $\%$ removal efficiency of A at steady$-$state for part c$?$

iv$.$ How does k affect the $\%$ removal efficiency?
