This is consistent with application of Le Chatelier’s principle. Effect of Changing Concentrations Changing the Volume of a Gas-Phase Reaction Mix A volume decrease (increase) of a gaseous reaction mixture at equilibrium will lead to a new equilibrium condition by net reaction that results in a decrease (increase) in the number of molecules in...
