BotanyCalculate the partial pressure of carbon monoxide from the following dataCaCO3(s)⇌ΔCaO(s)+CO2(g) ; Kp=8×10-2CO2(g)+C(s) ⇌ 2CO(g); Kp=2

Calculate the partial pressure of carbon monoxide from the following data
${CaCO}_{3} (s) \overset{Δ}{⇌} CaO (s) + {CO}_{2} (g); K_{p} = 8 \times 10^{- 2}$
${CO}_{2} (g) + C (s) ⇌ 2 CO (g); K_{p} = 2$

${CaCO}_{3} (s) \overset{Δ}{⇌} CaO (s) + {CO}_{2} (g); K_{p_{1}} = 8 \times 10^{- 2}$

${CO}_{2} (g) + C (s) ⟶ 2 CO (g); K_{p_{2}} = 2$

$K_{p}^{'} = K_{p_{1}} \times K_{p_{2}} = 8 \times 10^{- 2} \times 2 = 16 \times 10^{- 2}$

$K_{p}^{'} = {(p_{co})}^{2}$

$p_{co} = \sqrt{K_{p}^{'}} = \sqrt{16 \times 10^{- 2}} = 4 \times 10^{- 1} = 0.4 atm$
