← ScienceWhich mechanism enables a solid-state catalyst to accelerate a chemical reaction at elevated temperature?
A)Formation of higher energy intermediate structures
B)Increase in reactant molecule vibrational frequency
C)Decrease in surface area due to sintering
D)Reduction of the activation energy barrier✓
💡 Explanation
When reactants adsorb onto a solid-state catalyst, a new reaction pathway is formed by surface interactions, lowering the activation energy, thereby speeding up the rate of reaction. Therefore, reduction of the activation energy barrier result s, rather than higher energy intermediates, increased vibrations, or area decrease which impede catalysis.
