← ScienceWhich consequence results when hybrid orbitals mismatch catalyst's d-orbitals?
A)Increased reaction activation energy✓
B)Decreased catalyst surface area
C)Enhanced catalyst thermal stability
D)Accelerated product desorption rate
💡 Explanation
Reaction activation energy increases because poor orbital overlap reduces effective orbital interactions, inhibiting electron transfer during the catalytic process. Therefore, increased energy is required, rather than the catalyst thermally degrading, which is separate.
