I briefly mentioned that chemical reactions can go forward or backward, meaning that reactants form products and products re-create reactants. However, I then discussed chemical reactions as if they went only in the forward direction. I could get away with this because many chemical reactions go mostly forward, with only a smidgen of backward reaction.
Well, boys and girls, it's time to stop ignoring the backward reaction! In this section, we're going to learn all about chemical equilibria. Hold on to your hats!
