The composition of the equilibrium mixture $(Cl_2\iff2Cl)$ which is attained at $1200^{\large\circ}C$ is determined by measuring the rate of effusion through a pinhole . It is observed that at 1.80 mm Hg pressure , the mixture effuses 1.16 times as fast as krypton effuses under the same conditions. Calculate the fraction of chlorine molecules dissociated anto atoms.(Atomic wt of Kr = 84)
