← ScienceWhich consequence occurs when metal ligands weaken orbital overlap?
A)Increased catalytic reaction activation energy✓
B)Enhanced reducing agent redox potential
C)Improved structural material hardness
D)Higher superconductor critical temperature
💡 Explanation
Increased activation energy results because a weaker orbital overlap reduces electron delocalization, impairing the metal's ability to facilitate reactions as an effective catalyst via electron transfer; therefore, activation energy increases, rather than redox potential increasing because there are less overall electrons at the ligand interaction.
