Question

The decomposition of kclo3 proceeds spontaneously when it is heated. do you think that the reverse reaction, the formation of kclo3 from kcl and o2, is likely to be feasible under ordinary conditions? explain your answer.

Answer 1

The answer is No, it is not possible that the reverse reaction will occur at ordinary conditions. This is because the entropy of the KCl and the O2 are much largely negative than that of the KClO3. The entropy component of the Gibbs free energy assures that the Gibbs free energy for the reverse reaction is positive (Positive Gibbs means nonspontaneous reaction).
