← ScienceWhich outcome occurs when altering the reaction kinetics' Arrhenius constant?
A)Changes the reaction's activation energy
B)Shifts equilibrium constant values
C)Alters catalysis effectiveness directly
D)Modifies collision frequency factor✓
💡 Explanation
Altering the Arrhenius 'A' constant directly effects the pre-exponential factor (collision frequency) representing molecular collision rates, because the A constant influences reaction rate before activation energy is considered. Therefore, collision frequency modifies chemical reaction rates rather than affecting activation energy or equillibrium.
