Homework Help: Chemistry - Ideal Gas Law

  1. Oct 2, 2007 #1
    1. The problem statement, all variables and given/known data

    In general, which of the following gases would you expect to behave the most ideally?
    a) N_2
    b) CO
    c) H_2

    2. Relevant equations


    3. The attempt at a solution

    Okay, so I know that CO would definitely not behave the most ideally. I tried looking this up on the internet and I read that He would act the most ideally because it is the smallest molecule, and seeing how hydrogen is the next smallest, I think the answer is c) hydrogen gas but then I saw on another site that they said that nitrogen gas was the most ideal...so I am slightly confused. Anybody can shed some light please? Any help is appreciated.

    I wonder if the van der Waals equation and the correction factors could be used to rank the ideality of a particular gas?
