1. does le chatelier's principle only apply to reversible reactions?
2. No, it applies to reactions that go to a dynamic equilibrium...

For some reason the terms are interchangable for most I prefer your way though

Le Chatelier's principle is rubbish anyway

Explain things in terms of entropy changes and Kc

Only use Le Chatelier to check you've not done something stupid

Oh right! I was kind of thinking that water to ice is a reversible reaction because you can get water from ice but the reaction is not in dynamic equilibrium
5. You can apply the thinking to any equilibrium. It falls out of classical thermodynamics anyway, so it's not a complete fudge.

Ice and water can be in equilibrium, so pressure changes will affect the position of the equilibrium. Just as water can be in equilibrium with it's vapor.
6. wow you lot are smart !

..so I've come to the conclusion that in general the answer is le chartelier ISN'T just for reversible reactions ....but le chartelier is like almost basic so I shouldn't really be using it to describe particular things..instead I should use stuff such as 'entropy' ..w/e that is

Thanks

Dont answer questions about reactions that go to completion with anything about le chatelier because it doesn't work like that i.e only use it for equilibrium questions or you'll hemorrhage marks.
