← ScienceWhich outcome results when a palladium membrane selectively transports atomic hydrogen?
A)Hydrogen embrittlement within crystalline lattice✓
B)Spontaneous palladium hydride precipitation occurs
C)Increased membrane lattice compressive stress
D)Surface oxidation of palladium being catalyzed
💡 Explanation
Hydrogen embrittlement occurs because hydrogen atoms diffuse through the palladium via activated adsorption, facilitated transport and absorption inside palladium lattice causing internal crack propagation therefore embrittlement results rather than hydrides or surface catalysis limited diffusion.
