Heya guys

Err I just did the 2007 paper, and realised I borked basically the whole K question

So... I know K is dependant on temperature... but, when K is equal to [Products]^moles / [Reactants]^moles

Do you count solids? In the answer, solid sulfur was left out from this formula. So my question is...

1) Do you exclude solids? or...
2) Do you only count gases?

Thanks

Only gases and aqueous solutions count.

Do not count any without a concentration possible, ie. no such thing as concentration of Cu in Cu, nor concentration of Hg in Hg
