The composition of the equilibrium mixture (`Cl_(2)` `2Cl`) , which is attained at `1200^(@)C`, is determined by measuring the rate of effusion through a pin hole. It is observed that a `1.80 mm Hg` pressure, the mixture effuses `1.16 times` as fact as krypton effuses under the same conditions. Calculate the fraction of chlorine molecules dissociated into atoms (atomic weight of `Kr` is `84`).

Answer

0.14
