`Cl_(2)O^(7)` gas decomposes as:
`Cl_(2)O^(7)rarrCl_(2)+O_(2)`
`Cl_(2)O^(7)rarrCl_(2)+O_(2)`
A partially decomposed gaseous mixture is allowed to effuse through a pin-hole and the gas coming out initially was analysed . The mole fraction of the `O_(2)` was found to be 0.60. the degree of dissociation of `Cl_(2)O^(7)` will be:
