Why doesn't inert gas affect reaction rate?

Click For Summary

Discussion Overview

The discussion centers around the role of inert gases in chemical reaction rates, exploring why their concentration is often not considered a factor in these rates. Participants examine theoretical and conceptual aspects of this topic.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions why the concentration of inert gases, such as N2, is not included in reaction rate calculations, suggesting a possible confusion between reaction rate and space time.
  • Another participant proposes that the stable octet electronic structure of inert gases prevents them from participating in reactions, thus limiting their role in nucleation processes.
  • A different viewpoint emphasizes that by definition, inert gases do not react, and their presence primarily serves to dilute reactants, which could potentially influence reaction rates.
  • One participant expresses appreciation for the insights shared by others, indicating a collaborative exploration of the topic.

Areas of Agreement / Disagreement

Participants present multiple perspectives on the role of inert gases, with no clear consensus reached regarding their impact on reaction rates.

Contextual Notes

Participants do not fully explore the implications of dilution effects or the specific conditions under which inert gases might influence reaction dynamics.

Just as the title says, I'm having difficulty understanding why the concentration of inert gas is not included in the reaction rate. I would think adding a higher concentration of N2 (or some other inert gas) would increase the reaction rate. Perhaps, I'm confusing reaction rate with space time?

This is possibly because inert gases have stable octate electronic structure and hence cannot be sites(heterogenous) for nucleation which in other terms is reaction.
 
Because it's inert. By the very definition of inert it doesn't react. The only thing an inert gas can do is dilute the reactants and that might affect reaction rates.
 
Makes sense. Thank you pukb and Dr Morbius!
