← ScienceWhich outcome results when an inhibitor reduces the effective Arrhenius A-factor?
A)Reaction rate decreases exponentially✓
B)Activation energy threshold is lowered
C)Equilibrium shifts unexpectedly fast
D)Reverse rate becomes equally inhibited
💡 Explanation
A lower A-factor decreases the pre-exponential term because it limits collision frequency. Therefore, the reaction rate slows down exponentially, rather than altering the activation energy or equilibrium; those require catalysts altering different constants.
