Partial Pressure changes

[Irene Kang 3F]

If the partial pressure of a gas increased by a specific amount, do we assume that the other reactant in the same side of the gas also increased by the same amount? Just like how in an ice table the value x stays the same and so the increase in partial pressure would be just like x and the other compound will also increase by x if they are on the same side of the reaction?

Hi! From my understanding, as long as there is a 1:1 molar ratio between the two reactants, it would increase by the same amount X. Otherwise, I think that you would multiply a constant in front of the X based on the molar ratio values. I hope that helps!

[Monse Mata 3D]

I agree with the previous post, as long as there is a 1:1 molar ratio between the two reactants it should increase by the same amount X.

Yeah I agree. Partial pressure should change in similar ways to concentration for a given reaction. Since you can convert a partial pressure to a concentration, it wouldn't make sense for the partial pressures to change in a different way than the concentrations over the course of a reaction.

Irene,

Partial pressures are simply a description of the pressure in a system attributed to a particular gaseous species. Increasing the partial pressure of one reactant species (presumably through increasing quantity) has no bearing on the other reactant partial pressure initially. Once equilibrium is reestablished, you need to analyze the ICE table to determine final partial pressures.

it should increase by the same amount

Hi!
if the molar ratio between the reactants is 1 to 1, you can assume it would increase by X for both. if it is not the same ratio, multiply x by its multiplier and you will get the correct answer.
Hope this helps!

Yes, if you have two gasses on the same side of a reaction equation and one increases in partial pressure, assume that the other also increases at the according molar ratio

[Palig Kechichian 3F]

That depends on the molar ratio of the reactants!

[Edriana J Altea 2G]

It typically depends on the molar ratio so it should increase by the same amount.

[Isamar Aburto Paniagua 2K]

Depends on the molar ratio. Reactants with 1:1 ratio should increase by the same amount.
