Chemical Thermodynamics is the branch of chemistry that studies the relationships between heat, work, and energy in chemical processes. It helps us understand how energy is transferred during reactions and how it affects the properties of substances. By analyzing these energy changes, we can predict whether a reaction will occur spontaneously and how much energy will be released or absorbed. Key concepts in Chemical Thermodynamics include enthalpy, entropy, and Gibbs free energy. Enthalpy measures the total heat content of a system, while entropy quantifies the disorder or randomness. Gibbs free energy combines these factors to determine the feasibility of a reaction at constant temperature and pressure.
