Okay, we're given four different possibilities, and we want to know which one is true when we're at equilibrium in all cases.
00:09
And so i'm going to start with k is what i think it's probably the, well, i'm just going to start with k because i can.
00:19
So k is the equilibrium constant.
00:28
And it's a measure of concentrations of species.
00:37
And so basically it's going to be products, the concentration products over the concentration reactants is equal to k.
00:47
And so it's not saying if something's at equilibrium or not.
00:49
It's describing that equilibrium itself.
00:53
So this describes the equilibrium, or more accurately, the equilibrium conditions.
01:02
What conditions does your reaction need to be in order to be an equilibrium? not if at equilibrium.
01:12
So it finally measures the wrong thing to answer this question.
01:16
It's describing what the equivalent would be like, not if it's actually at those conditions.
01:22
So that is not going to be the answer for this question.
01:27
Delta h is our enthalpy, and this describes the energy, or more accurate, enthalpy, we often use it interchangeably, and for salts and liquids that effectively are, but for gases they're not really.
01:46
But loosely it's the energy needed or produced, consumed, and a reaction or phase change or something like that.
02:01
So this is describing how much energy we're consuming or producing...
