A chemistry student wants to investigate the effect of changing the volume on the equilibrium position for the reaction between nitrogen and hydrogen gas to form ammonia. If the student initially has 1 mole of nitrogen gas and 3 moles of hydrogen gas in a 2-liter container at equilibrium, and then decreases the volume to 1 liter while maintaining the same temperature, what will happen to the equilibrium concentration of ammonia in moles per liter?
