Question

Name the catalyst in the given case and write the chemical equation for

Decomposition of Potassium chlorate:

Answer 1

Catalayst: A catalyst is basically a substance that causes an increase in the rate of the reaction by decreasing the activation energy without itself being used up in the reaction.

Decomposition of potassium Chlorate:

• When the Potassium chlorate is heated in presence of a catalyst manganese dioxide leads to the formation of Potassium chloride and oxygen gas.
• The balanced chemical reaction can be represented as:

$\underset{\mathrm{Potassium}\mathrm{chlorate}}{\underset{}{2{\mathrm{KClO}}_3\left(\mathrm{s}\right)}}\underset{∆}{\overset{{\mathrm{MnO}}_2}{\to }}\underset{\mathrm{Potassium}\mathrm{chloride}}{\underset{}{\mathrm{KCl}\left(\mathrm{s}\right)}}+\underset{\mathrm{Oxygen}}{\underset{}{3{\mathrm{O}}_2\left(\mathrm{g}\right)}}$
