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,$2000K$

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

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