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.
