Calculate the particle pressure of carbon monoxide from the following `CaCO_3(s) overset(Delta)(rarr)CaO(s) + CO_2`
`overset(uarr , K_p = 8 xx 10^(-2))(CO_2)(g) + C(s) to 2CO(g) , K_p = 2`

Options

A. `0.2 `
B. `0.4`
C. `1.6 `
D. 4

Answer

B

Explanation

Given,`CaCO_(3(s))overset(Delta)rarrCaO_((s))+CO_(2(g))uarr`
`C_((s))+CO_(2(g))hArr,K_(p1)=pCO_2`
`Kp_2=([pCO]^2)/([pCO]),pCO=sqrt([Kp_1xxKp_2])`
`pCO = sqrt([8xx10^(-2) xx2]) =sqrt(16xx10^(-2))=4xx10^(-1)=0.4`
