If 50% of CO_(2) converts to CO at the following equilibrium : 1/2C(s) + 1/2 CO_(2)(g) hArr CO(g) and the equilibrium pressure is 12 atm Calculate K_(P).

Answer»

`4`
`7.5`
`1`
`14`

SOLUTION :`1/2C(s)+1/2CO_(2)(g) hArrCO(g)`
`{:("Initial mole",1/2,0),("Eq"^(n),1/2-1/2x,x):}`
`n_("total") = 0.25 + 0.5 = 0.75`
`K_(P) = (P_(CO))/(P_(CO_(2))^(1//2)) = ((0.5)/(0.75)xx12)/(SQRT((0.25/(0.075)) xx 12)`
`K_(p)= (0.5 xx 12)/(0.75 xx 2) = 2/3 xx 6 = 4`
