Dr. Lavelle established that increasing the pressure by decreasing volume results in the production of more products if there is more moles of gas on reactant side and more reactants if there are more moles of gas on product side. Will these trends be the same if we decrease pressure, such as if we were to expand the container of gas without adding more gas?
I believe the trends are the same, just in the opposite direction. So the reaction will shift to the side that has less moles.
Decreasing the pressure would cause the reaction to shift towards whichever side has more moles. Because of the pressure decrease and the volume increase, the concentrations would decrease resulting in the shift.
There will be the same effect on the equilibrium in the opposite direction. Decreasing the pressure (by increasing the volume) will push the equilibrium in the direction of the side with more moles of gas.
