Introduction to Enthalpy of Dissociation

The enthalpy of dissociation is a measure of the energy required to break a chemical bond in a molecule. In the context of the dissociation of oxygen gas (O2(g)), the enthalpy of dissociation is the energy required to break the double bond between the two oxygen atoms. This process is represented by the equation:

O2(g)→2O(g)O_2(g) \rightarrow 2O(g)

The Role of Bond Enthalpies

Bond enthalpies are a measure of the energy required to break a chemical bond. In the context of the dissociation of O2(g), the bond enthalpy is the energy required to break the double bond between the two oxygen atoms. The bond enthalpy is typically denoted by the symbol ΔH and is measured in units of kJ/mol.

Analyzing the Given Equation and Table

The given equation and table provide information about the dissociation of O2(g) and the bond enthalpies involved. The equation is:
