Help with Standard Enthalpy Change Calculation?
Calculate the standard enthalpy change of the reaction ClO(g) + O3(g) ---> ClO2(g) = 02(g)
Standard enthalpies are: ClO(g) is 101; for O3 is 142.3; for O2 is 0; for O(g), is 247.5.

We substitute the enthalpies for the reactants in the equation:
101 + 142.3 = ΔH + 247.5
ΔH = -4.2 kJ/mol
