Preparation of xenon difluoride
(i) It is prepared by the interaction of xenon with excess of `O_(2) F_(2)` at `- 118^(@) C`.
`Xe + O_(2) F_(2) overset(118^(@) C ) (to) Xe F_(2) + O_(2)`
(ii) It is also prepared by exposing a mixture of xenon and fluorine to ultra-violet light in a nickel vessel.
`Xe + F_(2) ("Ni vessel")/( UV) Xe F_2`
