Any reversible reaction can establish an equilibrium. The system in
which the reaction takes place must be closed to its surroundings
for an equilibrium to be established.
Equilibriums are important in a number of chemical and biological
Unit 2: Reaction Rates
This Unit Activity will help you meet these educational goals:
Science InquiryYou will explore the ozone layer by doing online research and
collecting information. You will then communicate your results in w
Le Chatelier's Principle
Recall that a chemical reaction reaches an equilibrium when the rates of forward and reverse
reactions are equal. At that point, the concentrations of reactants and products do not change.
You saw in the activity how changing the
Look at the picture on your screen and think about
the age of the tree.
The oldest living tree on Earth was found in Sweden
(You can read more about this tree if you wish.) It's
about 9,550 years old, meaning it took root at the end
What Does Chemistry Have to Do With Biology?
Chemistry students often wonder why they have to take chemistry to go into a medical field. I
have a few tidbits to mention that shows how chemistry can relate to our bodies.
