The following liquid$-$phase reaction takes place in a CSTR: A$+2$B $C$

The reaction rate expression is: $-r_A=k{C}_A{C}_B$

The total volume of the reacting mixture in the reactor remains constant throughout the process.

However, while species A continuously flows into the reactor, species B is loaded into the reactor at

the start of the operation. No more $B$ is added at any point during the operation. The residence time

of species $A$ in the reactor is $2$ minutes. The reaction rate constant is $1$Lmole$-1$min$-1.$ The

concentration of $A$ in the inlet stream is $50$ moles $\frac{?}{L}.$ The initial concentration of $B$ in the reactor is

$100$ moles$/$L$.$ There is no $C$ in the system at the start of the process.

Plot the change concentration profiles of A$,$ B and C in the exit stream of the reactor with respect to

time. Select the final time point in your graph to be $300$ minutes.
