If 50% of `CO_2` converts to CO at the following equilibrium:
`C(s)+CO_(2) (g)`
and the equilibrium presssure is 12 atm, calculate `K_(p)`.

Explanation

Initial pressure p atm
`C(s)+CO_(2) (g)Leftrightarrow 2CO(g)`
Equilibrium pressure : `(p-5p) " "p`
As given p-5p+p=12, p =8 atm
at equilibrium `p_(CO)=8atm`
`p_(CO_(2))=4atm`
`K_(P)=(p_(CO)^(2))/(p_(CO)_(2))=(8^2)/4=16"atm"`
