At a certain temperature and a total pressure of `10^(5) Pa`, iodine vapour contains `40%` by volume of `I "atoms"`, Calculate `K_(p)` for the equilibrium.
`I_(2(g))hArr2I_((g))`

Text Solution

Verified by Experts

Partial pressure of I atoms`(P_(I)) = 40/100 xx 10^(5)Pa = 0.4 xx 10^(5)Pa`
Partial pressure of `I_(2) atoms(P_(I_(2))) = 60/100 xx 10^(5)Pa = 0.60 xx 10^(5)Pa`
`K_(p) = P_(I)^(2)/P_(I_(2)) = (0.4 xx 10^(5))^(2)/(0.60 xx 10^(5)) = 2.67 xx 10^(4)Pa`
