Nitrogen gas reacts with hydrogen gas to form ammonia gas.  You have nitrogen and hydrogen gases in a 15.0-L container fitted with movable piston (the piston allows the container volume to change so as to keep the pressure constant inside the container).  Initially the partial pressure of each reactant gas is 1.00 atm.  Assume the temperature is constant and the reaction goes to completion.
 
   a)  Calculate the partial pressure of ammonia in the container after the reaction has reached completion.
   b)  Calculate the volume of the container after the reaction has reached completion.

Sorry...

Please don't delete the threat I am going to post my solution but I cannot do it right now.

Thanks!!!

O.K. now I am kinda lost  . This is what I've done so far.

We have 2 atm, nitrogen + hydrogen, and we have to end up with 2 atm, ammonia + nitrogen remaining(hydrogen is the limiting reactant).

N₂+3H₂--->2NH₃

a) The ratio is 2/3 so the partial pressure of ammonia will be about 0.67.

b) The initial volume was 15 L goes down by 1/3 so we end up with 5 L.

Is that the right answer???
