← ScienceWhich outcome results with increased Arrhenius pre-exponential factor?
A)Reaction rate constant increases✓
B)Activation energy requirements intensify
C)Kinetic isotope effect disappears
D)Equilibrium constant gets smaller
💡 Explanation
An increased Arrhenius pre-exponential factor directly influences the reaction rate via Collision Theory, because more molecular collisions will have proper orientation and energy profiles; therefore reaction rate increases, rather than decreases, as activation energy deals with the exponential term.
