← ScienceWhich consequence arises when a catalyst raises vibrational frequency?
A)Reaction equilibrium constant remains unchanged
B)Reaction rate increases towards equilibrium✓
C)Activation energy barrier rises significantly
D)Reactant concentration profiles flatten slowly
💡 Explanation
A catalyst forming a high-frequency vibrational mode on reactants changes the arrhenius equation, because a lower activation energy favors increased reaction rate, therefore faster speed rather than affecting product ratios defined by K rather than constant values.
