Question

The conversion of ozone to diatomic oxygen is represented by the equation above. Based on the data in the table above, what is the approximate average bond enthalpy for the oxygen-to-oxygen bonds in ozone?.

Answer 1

The approximate average bond enthalpy for the oxygen-to-oxygen bonds in ozone is 300 kJ/mol. The ozone is composed of three oxygen atoms, and it's highly reactive.

What is ozone?

Ozone is a light blue-colored gas, that is highly soluble in an inert, non-polar solvent.

$2O_3 \rightarrow 3O_2 \\\\ \Delta H = -300 KJ/mol$

There are double bonds present in the ozone, two molecules of ozone mean there will be four bonds.

$4 \times E -3 \times 500 = -300\\\\4 \times E = -300 + 1500\\\\E = \dfrac{1200}{4} \\\\E = 300 \;KJ/mol$

Thus, the correct option C, 300 kJ/mol.
