Gravity's effects on chemical reactions

Kyle Bosanko posed a GREAT question on my article last week about mapping out g on the moon. (My only regret is that I didn't get around to reading it until today! Sorry!) Here's Kyle's question:

I just finished up some chemistry homework and was wondering how much gravity [a]ffects chemical reactions. Would a reaction differ it were on the moon. I am particularly interested in reaction rates.
I'm not as familiar with gravity's impact on chemical reactions (though I suspect it's minimal), but I DO have a neat simulation to show you about a similar problem!

Gas Properties
Click to Run

This simulation (Just click it to run!) shows the behavior of an ideal gas, which is where gas particles roam freely until they bump into each other or the walls of the container. There's a slider that will allow you to adjust the strength of "gravity" (really, our g) to see what effects different levels of gravity have on the gas's behavior!

Enjoy!

  1. Wow! That's actually really interesting. I saw that as the gravity increase so did the activity of the gas particles.

  2. Exactly! What happens to the temperature as gravity increases? How might the difference in temperature affect a chemical reaction?

  3. This is awesome. Temperature skyrockets when there is an increase in gravity. Why does that happen? Temperature measures the average kinetic energy of particles so why do they speed up with an increase of gravity? I know when I experience more gravity I move less or work more to move at the same speed.

  4. I don't even know what I'm doing or why I'm doing it but that little program is really fun!!! I feel like I'm playing a video game.
