← ScienceWhich outcome increases when a catalyst degrades the d-orbitals?
A)Increased activation energy is required✓
B)Higher catalyst surface area results.
C)Substrate adsorption rates significantly increase
D)Product selectivity sees substantial improvement
💡 Explanation
Reduced interactions cause increased activation energy, because catalyst degradation diminishes the **orbital overlap** between reactant molecules and the catalyst d-orbitals; therefore, higher energy input is needed for reactions, rather than enhanced selectivity because of the destroyed structure.
