Equilibrium constant

Postby Deborah Cheng 1F » Tue Nov 21, 2017 11:50 pm

How do you find KP of a chemical reaction if the product is a solid?

To find K(p), the ratio would be 1/P(r). Since the molar concentration of a solid or liquid does not change in a reaction, solids and liquids aren't included in K expression. You would only need to find the concentration of the reactants.

With this, does that mean we completely disregard the solids and liquids when calculating the K constant? The gaseous reactants and products are the only ones used??

When calculating K, you should also include aqueous, but when calculating Kp, only gases are involved.

You should always disregard solids and liquids when calculating the value of K
