← ScienceWhich outcome occurs when iron catalyses hydrogen peroxide decomposition?
A)Lower activation energy accelerates decomposition✓
B)Increased enthalpy stabilizes reaction products
C)Elevated temperature favors peroxide formation
D)Reduced entropy enables chain propagation
💡 Explanation
Lower activation energy results from iron acting as a catalyst, decreasing activation energy according to Arrhenius equation, therefore increases the decomposition of H₂O₂ into H₂O and O₂, rather than forming alternative products or states, due to the catalysts pathway effect.
