At `800^(@)C,` the following equilibrium is established as
`F_(2)(g)hArr2F(g)`
The cojmpositionof equilibrium may be determinded by measuring the rate of effusion of theh kmixture through a pin hole. It is found that at `800^(@)C` and `1` atm mixture effuses `1.6` times as fast as `SO_(2)` effuse under the similar conditions. (At. mass of F =`19`) what is the value of `K_(p)` (in atm) ?
