why is average bond enthalpy of O2 is 495...But the formation enthalpy of O2 is 0 ??
Why are they different??
Why are they different??
Bond Enthalpy of Oxygen Gas, also known as Oxygen Bond Energy, is the energy required to break one mole of oxygen gas (O2) into its constituent atoms in the gas phase.
Bond Enthalpy of Oxygen Gas is measured in units of kilojoules per mole (kJ/mol) and can be determined experimentally by measuring the heat of reaction for the formation of oxygen gas from its constituent atoms.
Bond Enthalpy of Oxygen Gas is an important factor in understanding the stability and reactivity of oxygen-containing compounds. It can also be used to calculate the enthalpy change for a chemical reaction involving oxygen gas.
Bond Enthalpy of Oxygen Gas is relatively high compared to other bond energies, such as those of nitrogen gas or hydrogen gas. This is due to the strong covalent bonds present in the oxygen molecule.
Yes, Bond Enthalpy of Oxygen Gas can vary depending on the environment and conditions in which the measurement is taken. It can also vary slightly depending on the specific bond being broken (e.g. single, double, or triple bond).
