i Need help on this problem a step by step explanation for $1,2,$and $3$ would be helpful. I will leave a like

Consider the reaction $A2B(-r_A=k{C}_A^{0\mathrm{.}5},k=0\mathrm{.}021\frac{(\frac{\text{m}\text{o}\text{l}}{L}{)}^{0\mathrm{.}5}}{m}in)$ Products occurring

in a $200L$ semi$-$batch reactor. The reaction is started with a half$-$full reactor consisting of $2M$

species A$.$ For some strange reason, a $1M$ solution of $B$ is constantly fed at $1\frac{L}{m}in$ but there

is no flow out.

How long does it take for the reactor to be $90\%$ full?

What is the conversion of $A$ at this point?

What is the concentration of $B$ at this point?
