← ScienceWhich consequence follows if palladium is insufficiently cooled while absorbing substantial hydrogen?
A)Hydrogen embrittlement causes widespread cracking✓
B)Ionic bonding forms stable hydrides
C)Palladium converts into a superconductor
D)Increased chemical reactivity of palladium
💡 Explanation
Hydrogen embrittlement leads to cracking because small hydrogen atoms diffuse into the palladium lattice, weakening the metallic bonds. Therefore, embrittlement causes cracking, rather than increased chemical reactivity or the formation of stable hydrides.
