SUMMARY
The enthalpy of combustion for oxygen is defined as 0 KJ/mol because oxygen is a natural element that does not undergo a combustion reaction. When considering the enthalpy change for combustion, it is essential to recognize that combustion involves the burning of a substance in excess oxygen, and since oxygen itself does not burn, its enthalpy change remains zero. This concept is crucial for understanding thermodynamic principles in chemistry.
