Potential Energy Surface in chemical reaction computations

Click For Summary
SUMMARY

The discussion centers on the behavior of molecules adsorbed on a flat and defect-free potential energy surface during chemical reaction computations. It concludes that without a preferential path for reaction, the molecule is unlikely to undergo a reaction. Instead, it may either evaporate or be displaced by Brownian motion from surrounding gas particles. This highlights the significance of surface defects in facilitating molecular reactions.

PREREQUISITES
  • Understanding of potential energy surfaces in chemistry
  • Knowledge of molecular adsorption phenomena
  • Familiarity with Brownian motion principles

What would happen to a molecule adsorbed on a flat and defect-free potential surface? Would it just stay there? Or would it go somewhere?...I see it very difficult for the reaction to occur as no preferential path is present but this is just an intuition. Does anyone have an opinion/the answer?

Two things can happen: it will eventually evaporate or be thrown away by brownian motion of nearby gas particles.
