The Values of K and their Limitations

Postby 904940852 » Sat Dec 09, 2017 2:40 pm

For Ch. 11, I was told that K can only be used for gases and any solid or liquid could not be put into the equation. Is this true for Kc and all the other K values in Ch. 12, or do another set of rules govern both Kc and Ch. 12 K constant values?

Basically when you calculate the Kc or write Kc expression, you do not include solid and liquids as well as solvents.
And Ka, Kb and Kw also only includes aqueous solution.
Therefore the change in concentration of solids and liquids will not affect the Kc, Ka and Kb.
