Palladium dissociates molecular hydrogen easily through surface adsorption and low activation energy.
the verdict
SUPPORTED
the evidence backs this
confidence 87/100
Multiple studies demonstrate that palladium readily adsorbs and dissociates molecular hydrogen due to favorable surface energetics and low activation barriers.
