I need a step by step answer of question $1$ and $2$ and an explanation of how you got those results. Please, I will leave a like.

Consider the combustion of methane gas, $C_2{H}_6+\frac{7}{2}{O}_{2}2C{O}_2+3H_{2}O.$ The rate law:

$-r_A=2\mathrm{.}5C_A^{0\mathrm{.}5}{c}_B,$ where methane is A and oxygen is B$.$ Methane and air $($nitrogen$-$oxygen

mixture$)$ are fed to an isothermal $(328K),20L$ plug flow reactor at $5$atm. The total feed

flowrate is $25\frac{L}{m}in.$ The feed mole fraction of $C_2{H}_6$ is $0\mathrm{.}1,$ of $O_2$ is $0\mathrm{.}4,$ and the rest is nitrogen.

Plot the reactant and product molar flowrates and the volumetric flowrate as a function

of reactor volume

What is the exit conversion and concentration of ethane?
