← ScienceWhich outcome accelerates hydrogen peroxide decomposition containing platinum metal?
A)Lower activation energy reaction pathway✓
B)Increased reactant thermodynamic instability
C)Reduced solution dielectric permittivity
D)Enhanced product kinetic energy dissipation
💡 Explanation
Catalysis speeds up reactions through adsorption. The *lowering* of activation energy is the key *mechanism*, because the reaction proceeds via an alternative lower-energy state involving surface absorption; therefore, the reaction is then faster, rather than due to inherent instability or other bulk effects in solution.
