Which consequence results when palladium is heated under hydrogen?

A)Increased hydrogen absorption and interstitial storage
B)Palladium hydride decomposition to its elements
C)Palladium lattice destabilization and fracturing
D)Decreased solubility of hydrogen in palladium

💡 Explanation

Increased hydrogen absorption and interstitial storage occurs because heating palladium increases hydrogen atom mobility, therefore enhancing the diffusion rate into lattice sites. Hydrogen absorption into palladium expands the lattice spaces, rather than decomposition which need higher energy levels.
