← ScienceIn a palladium membrane hydrogen purifier operating above 300°C, which outcome results when hydrogen partial pressure increases?
A)Increased hydrogen permeation flux occurs✓
B)Palladium hydride phase transformations cease
C)Lower hydrogen dissociation on surface
D)Reduced hydrogen solubility in palladium
💡 Explanation
An increased hydrogen partial pressure drives a higher concentration gradient across the membrane, causing *Sieverts' law* permeation. Therefore, the permeation flux increases rather than solubility decreasing or phase transformations ceasing, because the membrane provides a path.
