Partial Pressure

Does increasing the partial pressure of one element, affect the partial pressure of another? Or does this only apply when increasing the overall pressure?

Re: Partial Pressure

Increasing the partial pressure of one element causes an increase in partial pressure on the other side of the reaction in order to minimize the effect of the change. This also applies when increasing the overall pressure, where the equilibrium shifts in the direction that decreases the number of molecules and lowers the pressure.

Re: Partial Pressure

If partial pressure of reactant is increased, then, the reaction will favor products to make up for the change and vice versa.
If overall pressure is increased, meaning that the volume decreased, the side with less gases will be favored (check the stoichiometric coefficients of the gases) and vice versa.

Re: Partial Pressure

changing the pressure will cause the reaction to shift to minimize the change, as per le chatlier's principle

Re: Partial Pressure

Increasing the partial pressure of something from one side causes the partial pressure of whatever else is on that same side to decrease and everything on the opposite side increases, and vice versa to maintain the proper ratio.

Re: Partial Pressure

Partial pressure works similarly to the way that concentrations do in le chatelier's principle. For example, if you increase the partial pressure of a reactant, the equilibrium will shift towards the products. Likewise if you decrease the partial pressure of a reactant, the equilibrium will shift towards reactants.
