Solution

Q.
${KMnO}_{4}$ decomposes on heating at 513K to form $O_{2}$ along with [2024]

1 ${Mn and KO}_{2}$

2 $K_{2} {MnO}_{4} {and MnO}_{2}$

3 $K_{2} {MnO}_{4} and Mn$

4 ${MnO}_{2} {and K}_{2} O_{2}$

Ans.
(2)

$2 {KMnO}_{4} (s) \overset{Δ}{\to} {MnO}_{2} (s) + K_{2} {MnO}_{4} (s) + O_{2} (g)$
