← ScienceWhich outcome occurs when a catalyst provides an empty molecular orbital?
A)Lower activation energy of reactants✓
B)Higher kinetic energy of products
C)Reduced potential energy from reactants
D)Modified vibrational modes of molecules
💡 Explanation
Lower activation energy facilitates reactions because the accepting empty molecular orbital allows electron density redistribution via a transition state. The change facilitates product formation more easily, therefore reaction quickens rather than modifying energy post-reaction.
