⚡ Enter ArenaWhy does a solid-state catalyst typically accelerate a reaction, even though reactants must transition to an adsorbed state?
A)Catalysts lower product energy states
B)Adsorption bypasses activation energy
C)Catalysts stabilize the transition state✓
D)Adsorption increases reactant concentration
💡 Explanation
A solid-state catalyst accelerates reactions because it stabilizes the transition state of the reaction on its surface, lowering the activation energy. Therefore, the reaction rate increases, rather than being hindered by the need for adsorption, or concentration increases.
