Calculate the partial pressure of carbon monoxide from the following data `:`
`CaCO_(3)overset(Delta)(hArr) CaO(s)+CO_(2) uarr ,K(p)=8xx10^(-2)`
`CO_(2)(g)+C(s) hArr 2CO(g), K_(p)=2`

Options

A. `0*2`
B. `0*4`
C. `1*6`
D. 4

Answer

B

Explanation

For reaction (i), `K_(p) = p_(CO_(2)) = 8 xx 10^(-2) ` (Given)
For reaction (ii), `K_(p) = (p_(CO)^(2))/(p_(CO_(2)))=2 ` ( Given)
` :. 2= (p_(CO)^(2))/(8 xx 10^(-2) ) or p_(CO) = 0.4 `
