Answer:
Shifts the equilibrium to side that has fewest moles of gas.
Explanation:
"Le Chatelier's principle", also called as the equilibrium law in chemistry explains the effect in different states on some chemical equilibria. It states that when a system is in equilibrium for a long time, it is subject to change in pressure, volume, temperature or condensation.
In this case, with an "increase" in pressure, there would be a shift to the side of fewer moles of gas. Mainly the change towards the reactants.
