Problem: Potassium chlorate
One of the common oxidizing agents in explosives,
fireworks, and match heads, undergoes a solid-state redox
reaction when heated. In this reaction, note that the
oxidation number of Cl in the reactant is higher in one of the
products and lower in the other (disproportionation):
4KCIO3(6) = 3KCIO:(s) + KCl(s)
Use AH° and S° values to calculate AG° at 25 °C.
Hint: Determine the thermodynamic entities from literature;
place them into Gibbs free energy equation and solve.
