Question

Complete the following reaction:

${\mathrm{KClO}}_3\stackrel{∆}{\to }$

Answer 1

Thermal decomposition:

• Some reactions occur only by heating.
• For example, potassium chlorate(${\mathrm{KClO}}_3$) decomposes only on heating.
• $\underset{}{\underset{\mathrm{potassium}\mathrm{chlorate}}{2{\mathrm{KClO}}_3}\stackrel{∆}{\to }}\underset{\mathrm{potassium}\mathrm{chloride}}{2\mathrm{KCl}\left(\mathrm{s}\right)}+\underset{\mathrm{oxygen}\mathrm{gas}}{3{\mathrm{O}}_2(\mathrm{g}})$
