← ScienceWhile storing hydrogen in metal hydrides, which consequence results when lattice vacancies increase?
A)Reduced hydrogen storage capacity occurs✓
B)Enhanced thermal conductivity is present
C)Faster intermetallic corrosion develops
D)Increased hydride formation enthalpy arises
💡 Explanation
Increased lattice vacancies reduce available sites for hydrogen atoms to occupy and form metal-hydrogen bonds and therefore capacity declines because hydrogen absorption depends on interstitial space rather than alternatives like lattice distortion.
