Partial Pressure vs Pressure

Postby MaryBanh_2K » Thu Jan 23, 2020 4:45 pm

When we look at the changes and effects using Le Chatelier's Principle, is Partial Pressure different from Pressure? For example, if the Partial Pressure of one of the products increases, will there be an increase in the Partial Pressure of the reactants. On the other hand, if Pressure increases in a reaction, does the reaction just shift to the side with fewer moles?

Yes, they are different. Also, if the pressure is increased by adding an inert gas, there is no change in concentration.

Partial Pressure more specifically is talking about the pressure one gas exerts, while pressure talks about the overall pressure exerted by all the gases in the container, So the partial pressure of all the gases in a container can be added to find the overall pressure.

The partial pressure and total pressure are different things, but they are related. The partial pressure is the pressure of a specific gas while the total pressure is the sum of all the partial pressures.

The summation of partial pressure gives the total pressure.

You can think of partial pressure as relating to individual reactants or products while pressure applies to the entire system simultaneously.

All of the partial pressures added together should result in the pressure.

Partial pressure is the pressure of one gas but pressure is the pressure of the whole system. All the partial pressures added together equals pressure.
