Webexample, let's look at molecular nitrogen in the air. Solvated N 2 is in equilibrium with N 2(g) and water. An equilibrium expression shows this. Because the system is in equilibrium, with rapid forward and reverse reactions, there will be an equilibrium constant that gives us information on the lowest energy state of the system.
WebJun 26, 2024 · If you're using argon in your manifold and cooling your trap with liquid nitrogen, you may condense argon in your trap. If then you close off your manifold without an outlet and the trap loses cooling, the manifold will be under intense pressure from the argon boil off. This presents a serious explosion hazard if you're not paying attention. Share
