Consider the following equilibrium reaction at a constant temperature: 2NO(g) + O2(g) ⇌ 2NO2(g)Initially, the reaction mixture contains 0.50 mol NO, 0.40 mol O2, and 0.10 mol NO2 in a 1.0 L container. The system is disturbed by contracting the volume to 0.50 L. Calculate the effect of changing the volume on the equilibrium position and calculate the concentration of each species at equilibrium.

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?
