Q$1.$ In a vacuum chamber at $0\mathrm{.}01$atm,$2000K,$ includes an ideal gas mixture of which mol

fractions are shown in the figure.

$CO2$ dissociates $CO$ and $O2$ molecules. Determine

a$)$ The balanced reaction equation for $1$kmol of $CO2.$

b$)$ Heat transfer amount for this reaction, in $k\frac{J}{k}$mol$-CO2.$ Is the

reaction endothermic or exothermic?

c$)$ Including entropy change of the chamber, determine total entropy

change of this reaction, in $\frac{k\frac{J}{K}}{k}$mol$-CO2$

d$)$ Solve the problem using EES

$0\mathrm{.}01$atm,$2000K$

$Y_{N2}=40\%,Y_{CO2}=40\%,Y_{O2}=10\%,Y_{CO}=10\%$

$C{O}_{2}CO+\frac{1}{2}{O}_2$

NOTE:There are already two solutions to this problem on chegg, but they are completely wrong. Please solve this with caution. Nitrogen is also included in the ratios given in the introduction of the problem. Therefore, it is important to include nitrogen when writing the equation of the reaction. It should be done as Co$2+?$O$2+?$N$2=$ Co $+....$ I also observe that enthalpy and entropy calculations are not made clearly.
