Question

Nitrogen gas (N₂) reacts with hydrogen gas (H₂) to form ammonia gas (NH₃). You have nitrogen and hydrogen gases in a 15.0-L container fitted with a 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 that the reaction goes to completion.  

1. Calculate the partial pressure of ammonia in the container after the reaction has reached completion.
2. Calculate the volume of the container after the reaction has reached completion.
