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.
