Question

Hydrogen peroxide, h2o2(aq), decomposes into water and oxygen. adding a small amount of fecl3(aq) increases the rate of gas evolution in this reaction. what is the best description of the role of fecl3?

Answer 1

I would call ferric trichloride a catalyst here. It increases the rate of the rxn.

Answer 2

• fecl₃ acting as catalyst-

iron (III) chloride is acts as the catalyst for the reaction which takes place in the transformation of hydrogen peroxide, H₂O₂(aq) into the two main products mainly water,H₂O and oxygen,O₂.

• The reaction is as follow:

• H₂O₂(aq)⇒ H₂O + O₂.

Step-by-step explanation:

• Catalysts-

A catalyst provide the best route or the easy path to start or initiate the reaction or the chemical transformation which leads to the speeding up the reactions.
