At a certain temperature and total pressure of `10^(5)` Pa, iodine vapours contains 40% by volume of 1 atoms.
`I_(2)(g) hArr 2 I(g)`
Calculate `K_(p)` for the equilibrium.

Text Solution

Verified by Experts

Total pressure of equilibrium mixture is `= 10^(5)` Pa
Partial pressure of iodine atoms (I) `= (40)/(100) xx 10^(5) = 0.4 xx 10^(5)` Pa
Partial pressure of iodine molecule `(I_(2)) = (60)/(100) xx 10^(5) = 0.6 xx 10^(5)` Pa
Also, `{:(I_(2)(g),hArr,2I(g)),((0.6xx 10^(5)Pa),,(0.4 xx 10^(5)Pa)):}`
