Kinetics with pressure

    This post is not about a homework problem but about a derivation
    When i was flipping through a physical chemistry book I found a formula which looked like

    How ever I am clueless to what it is

    Can anyone explain what it is for
    And possibly Derive it

    Thank you

    Flipping, eh ?
    Google first order reaction rate

    This must be for an isothermal reaction.

    In which case, when n = 1, if the pressure is P0 at the start what is it at t = ∞ ?

    The pressure kinetics is exceptionally easy, not to say degenerate. :oldlaugh:

    I dont know why I am that dumb but i haven't been able to derive it at all

    Maybe you are looking for something too clever or complicated.

    If all the chemical reaction is one molecule of A producing one of B, then there is just no change of pressure.
