Given:
ΔHo rxn = 296.2 KJ/mol
Hof(KClO3(s)) = -391.2 KJ/mol
Hof(O2(g)) = 0.0 KJ/mol
Balanced chemical equation is:
2 KClO3(s) ---> 2 KClO2(s) + O2(g)
ΔHo rxn = 2*Hof(KClO2(s)) + 1*Hof(O2(g)) - 2*Hof( KClO3(s))
296.2 = 2*Hof(KClO2(s)) + 1*(0.0) - 2*(-391.2)
Hof(KClO2(s)) = -243.1 KJ/mol
Answer: -243.1 KJ/mol
