If the volume of a reaction vessel containing N2O4(g) and NO2(g) at equilibrium is decreased, how will this affect the equilibrium position? Calculate the new equilibrium concentrations of N2O4 and NO2 if the initial concentrations were [N2O4] = 0.2 M and [NO2] = 0.4 M, and the volume is reduced by 50%. The equation for this reaction is: 

2NO2(g) ⇌ N2O4(g)
