How are xenon fluorides XeF2, XeF4 and XeF6 obtained?

Xe and F2 combine under different conditions to produce XeF2,XeF4,XeF6 as follows:
























Ratio



Temperature & Pressure Condition



Reaction



Excess



at {673K,1bar}



Xe(g) + F2(g) → XeF2(s)



1:5 ratio



at {873K,7bar}



Xe(g) + 2F2(g) → XeF4(s)



1:20 ratio



at {573K,60-70bar}



Xe(g) + 3F2(g) → XeF6(s)
