When I was a young boy I was kind of a philosopher I kept on asking questions But this one grabbed me the most Why is hydrogen dissociation Activated on copper But not on palladium I asked my mother why is that so She didn't know So I went to high school Got physics and chemistry I felt confident That finally they would tell me Why is hydrogen dissociation Activated on copper But not on palladium I asked my teacher why is that so (guess what) He didn't know (also) Later at the university I studied physics and chemistry The Schroedinger equation Would surely tell me Why is hydrogen dissociation Activated on copper But not on palladium I asked my professor why is that so (guess what) He didn't know (also, bad show, I wanna know) As a kind of a last resort I went to them orbitals Orbital, Orbital help me please Life ain't worth living anymore It is actually kind of easy When you use us orbitals First there is Pauli repulsion That may or may not be Reliefed And then finally you got the orbital relaxations That completes the story And that is that |
