← ScienceWhich condition decreases reaction rate when reactant potential energy increases?
A)Lowering the reaction vessel temperature✓
B)Presence of a homogeneous catalyst
C)Increasing the system's overall pressure
D)Stirring intensity within the vessel
💡 Explanation
Decreasing temperature lowers reaction rates because molecules possess less kinetic energy inhibiting overcoming the activation energy barrier; therefore, reaction rate drops rather than increases found through higher catalyst activity when temperature decreases.
