Given that a chlorine-oxygen bond has an enthalpy of 243 kJ/mol , an oxygen-oxygen bond has an enthalpy of 498 kJ/mol , and the standard enthalpy of formation of ClO2 102.5 kJ/mol , calculate the value for the enthalpy of formation per mole of ClO(g). What is the value for the enthalpy of formation per mole of ClO(g)?

Explanation:

The chemical equation is as follows.

And, the given enthalpy is as follows.

    ;   = 102.5 kJ

    Cl-Cl = 243 kJ/mol,      O=O = 498 kJ/mol

Since, the bond enthalpy of Cl-Cl is not given so at first, we will calculate the value of Cl-Cl as follows.

    102.5 =

    102.5 =

     102.5 - 12 =

           x = 181 kJ

Now, total bond enthalpy of per mole of ClO is calculated as follows.

              x =

                 = 339.5 - 243

                 = 96.5 kJ

Thus, we can conclude that the value for the enthalpy of formation per mole of ClO(g) is 96.5 kJ.

i think it is d. e because the next one is igneous.

the answer to this question is 3.
