While scaling relations offer numerous advantages, they also have limitations:
1. Applicability: Scaling relations often hold true only within specific material classes or under particular conditions. They may not be universally applicable. 2. Accuracy: The linear approximations used in scaling relations can sometimes lead to inaccuracies, particularly for complex reactions or materials with highly variable surface properties. 3. Non-linearity: Some catalytic systems exhibit non-linear behavior that scaling relations cannot accurately capture.
