← ScienceWhich outcome accelerates decomposition of concentrated hydrogen peroxide with a manganese dioxide catalyst?
A)Increased temperature intensifying kinetic energy✓
B)Decreased surface area lowering reaction affinity
C)Reduced concentration limiting reactant collision
D)Elevated pressure inhibiting decomposition rate
💡 Explanation
When temperature is increased, the kinetic energy of the reactants increases, leading to a greater number of molecules possessing the required activation energy to react on the catalyst surface. Therefore, heat leads to quicker decomposition, rather than decreased area which hinders catalysis, reduced concentration slowing collisions or pressure which plays minimal part.
