Given,${\text{CaCO}}_{\text{3}}\text{(s)}\stackrel{\text{Δ}}{\to }\text{CaO(s)}\text{+}{\text{CO}}_{\text{2}}\text{(g)}$
$\text{C(s)}\text{+}{\text{CO}}_{\text{2}}\text{(g)}\to \text{2CO(g)}$
${\text{K}}_{{\text{P}}_{\text{2}}}\text{=}\frac{{{\text{[P}}_{\text{CO}}\text{]}}^{\text{2}}}{\left[{\text{P}}_{{\text{CO}}_{\text{2}}}\right]}\text{;}{\text{P}}_{\text{CO}}\text{=}\sqrt{\left[{\text{K}}_{{\text{P}}_{\text{1}}}\text{×}{\text{K}}_{{\text{P}}_{\text{2}}}\right]}$
${\text{P}}_{\text{CO}}=\sqrt{\left[8\times {10}^{-2}\times 2\right]}=\sqrt{16\times {10}^{-2}}$
