At a certain temperature and a total pressure of `10^(5)` Pa, iodine vaour contain 40% by volume of iodine atmos `[I_(2) (g) hArr 2 I (g) ]. " Calculate " K_(p)` for the equilibrium.

Text Solution

Verified by Experts

Partial pressure of I atoms,
`p_1=(10^5xx40)/100=0.4xx10^5` Pa
Partial pressure of `I_2, =(10^5xx60)/100=0.6xx10^5` Pa
`K_p=p_I^2/p_(I_2)=(0.4xx10^5)^2/(0.6xx10^5)=2.67xx10^4` Pa
