Xenon tetrafluoride is prepared by heating Xe and in a nickel vessel under which conditions?

  1. AXe : = 1 : 20, 573 K, 60-70 bar
  2. BXe : = 1 : 1, 298 K, 1 bar
  3. CXe : = 1 : 5, 873 K, 7 bar
  4. DExcess Xe, 673 K, 1 bar

Answer: C

The standard conditions are: XeF2 from excess Xe at 673 K and 1 bar, XeF4 from a 1:5 ratio at 873 K and 7 bar, and XeF6 from a 1:20 ratio at 573 K and 60-70 bar. So XeF4 corresponds to the first option.
