nert xenon actually forms many compounds, especially with highly electronegative fluorine. The ΔH o f values for xenon difluoride, tetrafluoride, and hexafluoride are - 105, - 284, and - 402 kJ/mol, respectively. Find the average bond energy of the XebondF bonds in each fluoride.

For Xenon fluoride, the average bond energy is 132kj/mol

For tetraflouride, the average bond energy is 150.5kj/mol.

For hexaflouride, the average bond energy is 146.5 kj/mol

Explanation:

For xenon fluoride

105/2 = 52.5

For F-F

159/2 = 79.5

Average bond energy of Xe-F = 79.5 + 52.5 = 132kj/mole

For tetraflouride

284/4 = 71

For F-F

159/2 = 79.5

Average bond energy = 79.5 + 71 = 150.5kj/mol

For hexaflouride

402/6 = 67

F-F = 159/2 = 79.5

Average bond energy = 67 + 79.5 = 146.5kj / mol
