Use thermodynamic data to calculate the standard enthalpy change for the decomposition of water vapor to atoms in the gas phase. From this, obtain a value for the O–H bond energy. Similarly, obtain the standard enthalpy change for the decomposition of hydrogen peroxide vapor to atoms in the gas phase. Then, using the value you found for the O–H bond energy, obtain a value for the O–O bond energy. Compare these values with those listed in Table 9.5.
