A2 equilibrium constant questionWatch
and for heterogeneous reaction, if all is liquid and 1 solid do we leave out the solid, or if all was gas do we leave out liquid?
and if so why do we leave out solid and liquid ?
It gives some examples to demonstrate the exclusion cases.
Why do we write the activity of solids and pure liquids in equilibrium constants at standard conditions as 1?
The concept of activity is not in A level and just for interest.
Look on google, I would to see what you find, but as far as I know equilibrium constants are for gases and solutions
