Thermodynamics deals with energy changes in chemical reactions from "summary" of Chemistry by Russell Kuhtz
Thermodynamics is a branch of chemistry that focuses on energy changes in chemical reactions. In other words, it deals with how energy is transferred between substances as they interact with one another. This concept is crucial in understanding why and how chemical reactions occur, as well as predicting their outcomes. When substances react with each other, they can either release energy (exothermic reactions) or absorb energy (endothermic reactions). Thermodynamics helps us quantify these energy changes by using various parameters such as heat, work, and internal energy. By studying these changes, we can determine if a reaction is spontaneous or non-spontaneous under certain conditions. One of the key principles in thermodynamics is the First Law of Thermodynamics, which states that energy cannot be created or destroyed, only converted from one form to another. This principle is essential in understanding how energy is conserved in chemical reactions, as well as how it can be transferred between different forms. Another important concept in thermodynamics is entropy, which is a measure of the disorder or randomness of a system. In chemical reactions, entropy plays a crucial role in determining whether a reaction is likely to occur. For example, reactions that lead to an increase in entropy are more likely to be spontaneous, while those that decrease entropy are less likely to occur.- Thermodynamics provides us with a fundamental framework for understanding energy changes in chemical reactions. By applying the principles of thermodynamics, we can predict the direction and extent of reactions, as well as optimize conditions for desired outcomes. It is a powerful tool that enables chemists to explore and manipulate the world of chemical reactions.
