Will a change in pressure cause the reaction to shift one way or another?

Technically it will but in reality, it is the volume that is increasing/decreasing that makes the reaction shift.

Yes, in short it will cause the reaction to shift towards the side with the least amount of total molecules.

An increase in pressure will cause the reaction to trend towards the side with less moles so lets say we have a reaction that is 2A + 3B -> 2C then an increase in pressure will cause more products to form. This is true unless the pressure is increased by adding an inert gas (a gas that is random and not involved in the reaction), where then nothing would change.

Only if the volume is decreased/increase. If you're adding an inert gas that would technically change pressure but would not affect the equilibrium/ shift the equation.

Decreasing volume means an increase in pressure which would shift to the side with less moles of gas.

A change in pressure results in the reaction favoring the side with fewer moles of gas.

An increase in pressure means a decrease in volume, so equilibrium will shift to the side where there are less moles of gas.

If you increase the pressure, the reaction will favor the side with less moles.

Technically an increase in pressure will favor the side with less moles, but it also depends on other factors such as if it is an inert gas or if there is a change in volume with the reaction.
