Le Chatelier's Principle

What is the effect of increasing or decreasing the partial pressure of a reactant or product in a chemical reaction? How will we know which direction the reaction will shift?

If you increase the partial pressure of a reactant, the reaction shifts towards the products. If you decrease the partial pressure of a reactant, the reaction shifts towards the reactants.

I also think it is important to consider the fact that your solution depends on if pressure is increased by decreasing the volume of the container, or adding an inert gas.

If you focus on the inverse relationship pressure has with volume, that tends to help.
It will go to the side with fewer moles when volume decreases or pressure increases, and vice versa.

Decreasing the pressure of one side makes it go toward that side. Increasing the pressure of one side makes it go toward the other side.

I have a followup question: is there a difference between pressure and partial pressure in the context of this question?

if they increase pressure by adding an inert gas, it doesn't shift the chemical reaction either way (regardless of the moles of gas on each side of the chemical reaction)

If you increase the partial pressure on one side of the equation, the other side will be produced more and the reaction will shift to that side.

Increasing the partial pressure of a reactant shifts reactions towards the products, decreasing the partial pressure of a reactants shifts the reactions towards the reactants.

If you shift the partial pressure of the product, then equilibrium will shift to the reactants. If you shift partial pressure of a reactant, then equilibrium will shift towards the products. If you introduce an inert gas that is not involved in the chemical reaction then equilibrium will remain unchanged.

If you look at partial pressure as concentrations, if you increase the partial pressure of the reactants, the reaction will favor the products. If you increase the partial pressure of the products, the reaction will favor the reactants.

how do you calculate the partial pressure? and how does that relate to concentration?
