Question

The standard enthalpies of formation of ClO and ClO2 are
101 and 102 kJ/mol, respectively., Calculate the overall
enthalpy change for each step in the following catalytic
cycle:

What is the enthalpy change for the overall reaction that
results from these two steps?

 

ClO(g) + O3(g) ---->ClO2(g) + O2(g)
ClO2(g) + O(g) ---->ClO(g) + O2(g)
