Energy & Reaction Rates

In this unit, you’ll learn about how energy is transferred during chemical reactions (thermochemistry) and how fast that happens (reaction rate). Here are a few terms that you should be familiar with:

the study of matter and its transformations
the study of energy changes that accompany physical or chemical transformations
thermal energy
a form of kinetic energy that results from the motion of the molecules possessed by an object
chemical system
a set of reactants and products under study, usually represented by a chemical equation
