fig. $2.$ P$-$xy diagram of $C{O}_2-$water at $323K($experimental $[13]$ and calculated$).$

Refer to the attached figure, answer the following questions.

Write a MATLAB code and answers for below questions

What is the figure about?

What are the pressure ranges and temperature?

At $323K,8$MPa, what are the two phases of the mixture? What are the water mole

fractions of the two phases?

At $323K,8$MPa, which one listed in $(3)$ is a vapor phase, and which one is a liquid

phase?EXERCISE $5\mathrm{.}3\mathrm{.}1$: Reading a methanol$-$water P$-$xy diagram. The bubble and dew points of two$-$component mixtures containing methanol $($CH$\_(3)$OH$)$ and water $($H$\_(2)$O$)$ at $85$C can be summarized in a figure. metranui mule mactum $($a$)$ Label the liquid, vapor, and $2-$phase regions of the diagram. $($b$)$ The dew point pressure of a mixture containing $70$mol$\%$ methanol should be mmHg $.($c$)$ The bubble point pressure of a mixture containing $80$mol$\%$ water should be mmHg $.($d$)$ The vapor pressure for pure water at $85$C can be found from the P$-$xy diagram as mmHg $.$
