I want to mention one last important note what will happen if we add some other arbitrary molecule that is not present in our reaction? Such as for example, diatomic CO2 in our gas state? Well, to answer this question, let's look at our partial pressure equilibrium constant. And the reason we're using partial pressures is because every single reactant is in the gas state. Let me just add the G and G for gas. So our equilibrium or partial pressure equilibrium constant given by KP equals the partial pressure of our product to the second power because we have a two coefficient divided by the partial pressure due to this gas molecule times the partial pressure due to this gas molecule to the third power.
