Question

is the catalyst used in the reaction $2H_2{O}_2\to 2H_{2}O+O_2$

• A. ${\mathrm{CuSO}}_4$
• B. ${\mathrm{FeSO}}_4$
• C. ${\mathrm{NH}}_4\mathrm{OH}$

Answer 1

The correct option is B ${\mathrm{FeSO}}_4$

A catalyst is a chemical compund which alters the rate of a reaction without itself undergoing any chemical change. Catalysts are used in chemical reactions to increase or decrease the rate of reaction.
The catalyst used for the given reaction is $FeS{O}_4$. It increases the rate of decomposition.
