← ScienceWhich rate outcome occurs when inhibitor reduces effective collisions?
A)Equilibrium constant increases substantially
B)Reaction rate constant decreases✓
C)Enthalpy change becomes exothermic
D)Gibbs free energy lowers drastically
💡 Explanation
The reaction rate decreases because the presence of an inhibitor reduces effective molecular collisions disrupting activation energy, therefore the rate constant decreases, rather than equilibrium shifts or energy changes, as the inhibitor directly impacts kinetics.
