Question

Mention catalyst in the following reaction:

$KCl{O}_3\to KCl+O_2$

• A. $Mn{O}_2$
• B. $FeC{l}_3$
• C. $PdC{l}_2$
• D. $ZnO/CuO$

Answer 1

The correct option is A $Mn{O}_2$

Option (A) is correct.

The catalyst used for the reaction $KCl{O}_3\to KCl+O_2$ reaction is $Mn{O}_2$.The $Mn{O}_2$, causes the reaction to take place more rapidly at a lower temperature.

The given reaction is a decomposition reaction of potassium chlorate used to obtain oxygen.
