Answer

The entropy of the system is increasing because the reactants contain a gas. Recall gas particles are in constant motion and have higher entropy than the other phases: (liquid and solid). The entropy of the reaction is decreasing because gases in the reactants are being transformed into solids. Solids are alot less disordered than gos molecules which are in constant motion.
