← ScienceWhich mechanism reduces the energy needed for forward reaction in catalytic converters during automobile exhaust processing?
A)Lowering activation energy via surface adsorption✓
B)Increasing reactant concentration using a diffuser
C)Raising reaction temperature through heat exchange
D)Shifting equilibrium via Le Chatelier's principle
💡 Explanation
When exhaust gases flow through a catalytic converter, surface adsorption lowers the activation energy because the catalyst provides an alternative reaction pathway with a lower energy barrier, increasing the reaction rate. Therefore lowered activation results, rather than concentration increase, temperature control, or equilibrium shifts which would require external systems.
