The first link shows why when you add reactions to get another reaction you<br>
multiply the equil. constants. I told you to prove this to yourself.<br>
<br>

<br>
The 2nd link is the first example I did where I ignored the "x". I've made a video<br>
using my notes working through the example while explaining things. There's<br>
three pages. <br>

<br>
The 3rd link is the second example I did where the reaction was going in the<br>
reverse direction, with the "-" signs on the right-hand side of the ICE table.<br>
I did it both ways, going right to left and then reversing it and going left to<br>
right. You'll see you get the same answer doing it either way.<br>

<br>
The 4th link is a video of the NO2/N2O4 equilibrium and LeChatelier's Principle<br>
(the one in the syringe with the brown gas). I showed this in class.<br>
