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

Text Solution

Verified by Experts

Partial pressure of I atom `(rho_1) `
` " " = (40)/(100) xx 10 ^(5)`
` " " = 4.0 xx 10 ^(4) Pa`
Partial pressure of `I_2 (rho_(I_2))`
` = ( (100 - 40))/(100) xx 10 ^(-5) = 6.0 xx 10 ^(4) Pa`
` therefore " " K_p =(rho_(I) ^(2))/(rho_ (I_2) ) = ( (4.0 xx 10^(4))^(2))/(6.0 xx 10 ^(-4) ) = 2.67 xx 10 ^(4)`
