Thermochemistry is a branch of chemical thermodynamics , the science that deals with the relationships between heat, work, and other forms of energy in the context of chemical and physical processes. As we concentrate on thermochemistry in this chapter, we need to consider some widely used concepts of thermodynamics. Substances act as reservoirs of energy, meaning that energy can be added to them or removed from them. Energy is stored in a substance when the kinetic energy of its atoms or molecules is raised. The greater kinetic energy may be in the form of increased translations travel or straight-line motions , vibrations, or rotations of the atoms or molecules.

The temperature of the calorimeter plus contents increases from The heat of the reaction delta E is the delta T multiplied by the heat capacity of the calorimeter. So it is 5. We then divide this value by the moles of phenol 1.
