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

A second$-$order reaction $AB$ with $-r_A=k{C}_A^2$ must be carried out in a $60,000L$ CSTR$.$

The volumetric flowrate and feed concentration of A are $5\frac{L}{h}$ and $0\mathrm{.}5M,$ respectively.

Plot the time$-$dependent concentration of A until it reaches steady state.

What is the time needed to achieve steady state?
