How well do you know the relationship between enzymes and activation energy? This resource provides you with short quizzes and tutorials to provide feedback for those topics you don't understand.

Acting as an overview from the General Chemistry Virtual Textbook, this site explores equilibrium and equilibrium constants in reference to dilution. Formulas and charts are also provided on the subject.

[Free Registration/Login may be required to access all resource tools.] Students explain the factors that stress a system at equilibrium and use Le Chatelier's principle to predict how the system will respond to each stress. They will...

Learn about weak acid and base ionization reactions and the related equilibrium constants, Ka and Kb. Relate Ka and Kb to pH, and calculate percent dissociation.

[Free Registration/Login may be required to access all resource tools.] Students write the solubility product constant expressions for nearly insoluble ionic compounds and perform calculations for compounds and solubility.

Determine the temperature required to keep a piston in equilibrium. You must use information about the speed of the atoms in the left hand chamber to help you find the equilibrium pressure.

Learn where acids and bases fall on the pH scale and the correlation between hydrogen and hydroxide ions. See many examples of how to calculate the pH of a substance. Also find links to the chemistry textbook and tutorials.
