The Shortcut Needs a Gate

You'll learnhow to find equilibrium concentrations from K, and when the easy shortcut is allowed.

A sealed flask starts with one gas and nothing else. It will settle somewhere, and K is the number that says where. There is an easy way to find it and a hard way, and one short check decides which one you are allowed to use. Twelve short steps; press Next for each one.
