Le Chatelier and water

Postby Arianna Ko 2E » Tue Jan 22, 2019 9:42 pm

If you add water, does this effect in whether reaction will form reactant and product? Same for if you remove water, because water is a liquid, so does it have an effect on K.

Since we don't include liquids or solids in K-values, adding water won't change the K-value.The only thing that would affect it is if the concentrations of the reactants or products are increased/decreased, but if the concentrations remain the same, adding water won't affect it.

Water in liquid form would not affect the Q or K of a reaction. Because water(l) doesn't affect Q, if you added water to a system at equilibrium, the Q would equal K, meaning the system remains at equilibrium.

This is only if water is in liquid form. If it is a gas then you would use that in calculations for Q and K.

I believe that water in a gas form would effect the resulting K value. However liquids and solids aren't included in K expressions and therefore have no effect on the K value
