After working on the problem some more; I found that there is a simple way to do the problem. Simply find the mole fractions with the number of moles given and calculate the total pressure with PV = nRT for 3 moles, and 22.4dm^3. Not much more to it than that. The solution in the book...

[SOLVED] PCHEM/Partial Pressures Question Problem Statement: A vessel of volume 22.4dm^{}3 contains 2.0 mol H_{}2 and 1.0 mol of N_{}2 at 273.15K initially. All the H_{}2reacted with sufficient N_{}2 to form NH_{}3. Calculate the partial pressures and the total...

Thanks a bunch. This site rocks. (thank you)^(10)

This means that v must equal" v= (re^-(ar^2))/-2ar in order for us to get the dv back right? THANK YOU FOR THE QUICK REPLY :) !
