Chemical thermodynamics is the branch of physical chemistry that deals with the energy changes and equilibrium states of chemical reactions. It provides insights into the feasibility and spontaneity of reactions by analyzing the relationships between heat, work, and internal energy within a system.

Chemical Thermodynamics

Chemical thermodynamics

Physical chemistry bridges the gap between physics and chemistry, focusing on the physical properties and behavior of matter at the molecular and atomic level. It employs principles of physics to understand chemical systems and reactions, providing a fundamental basis for both theoretical and experimental chemistry.

energy changes

Equilibrium states refer to conditions in which a system experiences no net change over time, often representing a balance of forces or energy. These states are crucial in understanding phenomena across various fields, such as physics, chemistry, and economics, where they help predict system behavior under different conditions.

equilibrium states

Chemical reactions involve the transformation of substances through the breaking and forming of chemical bonds, resulting in the conversion of reactants into products. These reactions are governed by the principles of thermodynamics and kinetics, which dictate the feasibility and rate of these transformations.

Work is a fundamental economic activity that involves the expenditure of effort to produce goods or provide services, typically in exchange for compensation. It is a central component of human life, influencing social structures, individual identity, and economic systems.

work

Internal energy is the total energy contained within a system, encompassing both kinetic and potential energy at the molecular level. It is a state function, meaning its change depends only on the initial and final states of the system, not on the path taken to get there.
