Solid carbon, CaO and $\mathrm{CaCO}_3$ are mixed and allowed to attain equilibrium at TK . $$ \begin{aligned} & \mathrm{CaCO}_3(\mathrm{~s}) \mathrm{f} \quad \mathrm{CaO}(\mathrm{~s})+\mathrm{CO}_2(\mathrm{~g}) \quad \mathrm{Kp}_1=0.08 \mathrm{~atm} \\ & \mathrm{C}(\mathrm{~s})+\mathrm{CO}_2(\mathrm{~g}) \mathrm{f} \quad 2 \mathrm{CO}(\mathrm{~g}) \quad \mathrm{Kp}_2=2 \mathrm{~atm} \end{aligned} $$ The partial pressure of CO is $\_\_\_\_$ $\times 10^{-1} \mathrm{~atm}$
