Why doesn't inert gas affect reaction rate?

  1. Nov 26, 2011 #1
    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!
