Questions:

a$)$ What are the order $(n$ and rate constant $(k)$ of this reaction?

b$)$ In a $100L$ volume CSTR reaction vessel initially filled with $24$mmo$\frac{l}{L}$ of $A$

substance, only the outlet stream is taken with a flow rate of Qout $=4\frac{L}{m}in.$

What is the outlet stream B substance concentration at the $20$th minute and

when the reactor is completely emptied?
