LeChatelier's Principle 2 obeys the same principle as LeChatelier's Principle 1. However, here we see the physical effects of the principle. The model simulates how chemists are able to physically separate chemicals from one another across a membrane. Altering the variables of temperature, volume and concentration allows the the students to observe the effects on a systems that is chemically inert.

For detailed instructions on using the program, take a look at the info window from the LeChatelier Principle 2 model.
