← ScienceWhich consequence results when molecular orbitals become decoupled?
A)Decreased catalytic efficiency
B)Increased activation energy✓
C)Enhanced thermal stability
D)Reduced radiative emission
💡 Explanation
Decoupling disrupts electron delocalization; therefore, orbital mixing decreases and activation energy increases because the reactants must overcome a larger energy barrier to form products, because resonance stabilization is lost rather than enhanced.
