Which outcome occurs when powdered iron is added to hydrogen peroxide?

💡 Explanation

The addition of powdered iron speeds up decomposition via surface catalysis by increasing the decomposition reaction rate, because the iron acts as a catalyst, lowering the activation energy of the reaction; therefore, the reaction is faster rather than resulting in a change in equilibrium.
