← ScienceWhich outcome occurs when a platinum catalyst is introduced into a hydrogen peroxide decomposition reaction?
A)Activation energy requirement decreases notably✓
B)Changes in the enthalpy become positive
C)Equilibrium shifts towards reactants favored
D)Reaction order is exponentially reduced down
💡 Explanation
Adding a platinum catalyst provides an alternative pathway with lower activation energy through surface adsorption; because of lower energy requirements the reaction goes faster, therefore the activation energy is decreased rather than the reaction order being changed.
