Please refer to the “General Study Sheet” Post for information regarding the exams THERMOCHEMISTRY CHAPTER 6 INTRODUCTION Thermochemistry is a facet of chemistry which combines reaction writing, completion, and balancing with the heat or energy absorbed or released in the chemical reaction. In essence, you might say that the energy in a reaction is a product or reactant normally hidden from the person writing the reaction. This chapter introduces a way to determine both theoretically (Hess's Law) and experimentally (calorimetry) the energy change (enthalpy) in a chemical reaction. We are concerned in this chapter with the change in internal energy of a system as it goes through any change—chemical or physical. In chemistry we define our signs from the point of view of the system with heat lost by system, q, or work, w, done by the system being negative and heat gained by the system or work done on the system being positive.
