Gas Pressure and Molecular Mass
The ideal gas equation (or the van der Waals equation, for this matter) states that holding volume and temperature constant, increasing the number of moles of particles in the container will increase ...

Where does this equation for the activity in the gas phase equilibrium between N₂, H₂ and NH₃ come from?
I have a question with Equilibrium Constant.
I understand that for a reaction in equilibrium $aA +bB \rightleftharpoons cC +dD$
$$K_c= \frac{[C]^c[D]^d}{[A]^a[B]^b}$$
and $K_p$ is just using the ...

How to calculate the equilibrium constant from the density of a nitrogen dioxide and dinitrogen tetroxide mixture?
The density of an equilibrium mixture of $\ce{N2O4}$ and $\ce{NO2}$ at $\pu{1 atm}$ and $\pu{373.5 K}$ is $\pu{2.0 g/L}$. Calculate $K_c$ for the dissociation reaction
I did this:
Let initial amount ...

Addition of inert gas at "constant volume"?
My textbook states that
"The addition of inert gases at constant volume does not affect the equilibrium state of the reactants and products contained in that volume."
Although I am not ...

How can I calculate the percentage of dissociated dinitrogen tetroxide?
When $\pu{36.8 g}$ $\ce{N2O4(g)}$ is introduced into a 1.0-litre flask at $\pu{27 °C}$ the following equilibrium reaction occurs: $\ce{N2O4(g) <=> 2NO2(g)}$; $K_p = 0.1642~\mathrm{atm}$.
Find ...

Pressure dependency in Haber Bosch ammonia synthesis
Haber-Bosch ammonia synthesis reaction:
$$\ce{3H2 +N2 -> 2NH3}$$
According to the ideal gas law: $pV=nRT$ where constant volume implies $\displaystyle \frac nV=\frac p{RT}$
Then $\displaystyle ...

Measure of partial pressure on blood
Here is the issue of blood gases partial pressure.
On medical reports is common to see partial pressure of gas on blood, usually oxygen, but there is no gas in equilibrium with blood, so it is ...
