Equilibrium in the semi-dark

Today we looked at a couple additional equilibrium problems and behavior including:

The similarities, differences and conversion between concentration-based equilibrium constants (Kc) and pressure-based equilibrium constants (Kp). They're related by the ideal gas law!

How do we determine if a reaction is at equilibrium? The reaction quotient has the same mathematical form as the equilibrium constant and can tell us where a reaction is relative to equilibrium.

What happens when we push around a system that's at equilibrium? If experiences stress, and it squirms around until it relieves that stress. This is LeChatelier's Principle and it can be used to explain chemical equilibria, human behavior, economic trends, population dynamics, and a whole lot more.

There's a new Mastering Chemistry assignment posted, due Monday. There's also a MC due Friday, so keep up with them.

This weekend the MSUM women's basketball team is going pink to put a full court press on breast cancer. T-shirts are available at the bookstore, and the 21st-ranked Dragons would love to see a mountain of pink in the stands at their game against Concordia (St. Paul) on Saturday. This is one of the last home games of the regular season, so come and cheer the Dragons into the post season.

See you all on Friday, the lights should be working again in SL104 by then....
