Pressure

Which direction does the reaction go when there's increased pressure?

When there is increased pressure, the reaction will favor whichever direction has fewer moles of product. For example, for the reaction Cl2 <-> 2Cl, if the pressure were increased at equilibrium, the reverse reaction would be favored since there is only one mole of Cl2 for every two moles of 2Cl.

it goes to the side with less moles.

It depends entirely on the number of moles on the different sides of the equation. An increase in pressure will favor the side with less gaseous moles.

An increase in pressure will favor the side of the reaction with less moles of gas and an decrease in pressure will favor the side of the reaction with more moles of gas. However, if an inert gas is added to the system, there is no change in the reaction.

It depends on which side of the equation has more moles of gas. If the reactants have more moles of gas and pressure is increased, the reaction will shift to the right to lower the pressure and re-reach equilibrium.
