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_(1))`
`=40/100xx10^(5) Pa=0.4xx10^(5) Pa`
Partial pressure of `I_(2)(p_(I_(2)))=60/100xx10^(5) Pa=0.60xx10^(5) Pa`
`K_(P)=p_(I)^(2)/p_(I_(2))=((0.4xx10^(5))^(2))/(0.60xx10^(5))=2.67xx10^(4)`
