Predicting if a Reaction is in Equilibrium Trial Keq Lesson 9

By: Crystal & Caitlin! :D. Endothermic Reaction: a reaction in which the products have more stored energy than the reactants. The reaction absorbs energy

Chemical Reactions. Reactants: –A starting substance in a chemical reaction. Products: –A substance formed in a chemical reaction

Bell Ringer. Chemical Equilibrium A reversible reaction is one in which the reactants are changing into products and products are changing into reactants

Chapter 14. Physical state of reactants: Reactants must come in contact with one another in order for a reaction to occur. Concentration of reactants:

Reaction rate How quickly or slowly reactants are turned into products is called the reaction rate

Equilibrium Expression (Keq) Also called “Mass Action Expression” Also called “Mass Action Expression” Relates the concentration of products to reactants

Reaction Rate (aka – Chemical Kinetics) Reaction rate – how fast reactants disappear and how fast product appears
