The equilibrium expression is going in a generic form is that your k equals your products over your reactants.
00:11
All right.
00:12
And of course, if there's any like coefficients or anything, they come in as exponents.
00:17
And so there's a couple things to note.
00:19
Well, let's get this written down first.
00:21
Sr co3 as a solid going back and forth to sro as a solid and co2 as a gas.
00:29
I have an idea as to why you're asking this question, actually.
00:33
There's a bit of a trick to it.
00:35
So the one thing to remember is that pure solids and pure liquids do not appear in the equilibrium expressions.
00:44
In fact, we just set them equal to one.
00:49
Aqueous still goes in your k expression, and so does your gas...
