Of course, HSC does not solve all chemical problems, because it does not take into account the kinetics (rates) of the chemical reactions and non-ideality of solutions. However, in many cases it is a very inexpensive and useful tool which helps to find the optimum reaction conditions and ...
calculations, we find that thesequantum-mechanical simulations reveal a qualitatively different picture.Recombination of adsorbed H atoms, which was believed to be irrelevant at lowtemperature due to high barriers, is enabled by deep tunnelling, with reactionrates enhanced by tens of orders of ...

I 27. Brittany: Yeah, cause they will dissociate in whatever you put it in, and you will get a reaction … If they’re weak, they won’t break apart C 28. Farrah: Weakly dissociate, got it. A 29. Jasmine: So, a better leaving group equals A 30. Brittany: Um, more reactive A...

with reactionrates enhanced by tens of orders of magnitude. Furthermore, we identify a newpath for H recombination that proceeds via multidimensional tunnelling, butwould have been predicted to be unfeasible by a simple one-dimensionaldescription of the reaction. The results suggest that hydrogen mole...
