The enthalpy change for the following reaction is -318 kJ.

OF2(g) + H2O(g) --> O2(g) + 2HF(g)

a) To analyze the reaction, first draw Lewis structures for all reactant and product molecules.

b) Estimate the O-F bond energy in OF2(g) , using tabulated bond energies (linked above) for the remaining bonds.

Bond data for question two can be found in a references chart by googling bond energy (will not allow photo upload)

H - O = 463kJ

O=O = 498kJ

H-F = 565kJ
