Can anyone explain me catalytic rection? For example disociation of molecule H₂ at surface of Pt. I know that catalytic material stays as it is without reaction..it just burst the chemical reaction. Also I know that the electrostatic bonds which are between H-H atoms are disturbed and this implies to disociation. But why they are disturbed? Cant find it over the net. Anyone can help me? Thank you!

Catalysts typically work by lowering the activation barrier of a reaction.

i need a little deeper explanation

Catalyst mechanisms are complicated and not straight forward. This year's nobel prize was given in part to the studies on surfaces like the one you've asked about. Look up the work of Gerhard Ertl.

Dear SkiPY;

For the first steps you may read: "Catalysis”

Good Luck!
