Question
What happens when Xe (g) is heated with dioxygen gas in a sealed tube?
Options:
A .  Only XeO3 is formed
B .  Initially XeO3 is formed which slowly gets oxidized to XeO4
C .  A mixture of both XeO3 and XeO4 is obtained 
D .  No reaction
Answer: Option D
:
D
For the reaction,
Xe(g)+O2(g)xenon oxidesΔfG > 0
In other words, the standard change in free energy of the reaction is positive. Hence, this reaction is non-spontaneous. None of the Xenon oxides can be synthesized from this approach. So how can they be obtained?
