← ScienceWhich outcome results when a catalyst with low activation energy lowers the surface energy in a chemical reaction?
A)The thermodynamically unfavorable product forms
B)The reaction rate reaches diffusion limit✓
C)The active site undergoes self-poisoning
D)The equilibrium constant becomes temperature independent
💡 Explanation
When a catalyst with low activation energy lowers the surface energy, heterogeneous catalysis accelerates because the reaction proceeds via the most energetically favorable pathway, significantly increasing the rate of product formation until mass transport limits are reached. Therefore the reaction rate reaches the diffusion limit, rather than unfavorable product, poisoning, or temperature independence requiring specific equilibrium shifts.
