### Partial Pressure and Moles

When increasing and decreasing partial pressure and concentration in a chemical equilibrium reaction, does the number of moles matter? or do they only matter when considering increasing or decreasing pressure on the whole system?

When there is a change in pressure, the volume of the system is usually changing; the amount of matter in the reaction vessel remains the same, but the amount of space (volume) that the matter takes up is partially related to the pressure being placed upon the matter. It is important to notice that the amount of matter is not changing, but instead, it is becoming more or less concentrated depending on how the volume is changing. When the concentration is changing, then there will be a shift in the current state of the system in order to reach equilibrium again.

Can you make an ICE table for partial pressure or is just used for concentration?
