- "Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling."
The study of the relation between heat and other forms of energy in chemical reactions.
Energy: This topic covers the basic concept of energy and its various forms like potential, kinetic energy, and internal energy.
Calorimetry: This involves the measurement of heat exchanged between a system and its surrounding environment.
Enthalpy: It describes the measurement of heat flow in a reaction taking place at a constant pressure.
Heat capacity: This topic refers to the amount of heat required to raise the temperature of an object by one degree.
Heat of formation: This concept measures the amount of heat evolved or absorbed during the formation of a compound from its constituent elements.
Hess's law: This law states that the amount of heat generated or consumed during a chemical reaction is independent of the path taken, and only depends on the initial and final states of the system.
Bond Energy: It measures the energy required to break a chemical bond.
Reaction spontaneity: This topic is concerned with the prediction of reactions that occur naturally or spontaneously based on their thermodynamic properties.
Thermochemical Equations: These are balanced chemical equations that depict the enthalpy changes associated with the reaction.
Gibbs Free energy: It describes the change in free energy that occurs during a reaction. This energy is used to predict the spontaneity and direction of a reaction.
Standard state: This is a reference state where values of thermodynamic properties are defined and tabulated.
Entropy: This is a measure of the degree of disorder or randomness in a system, and it is used to predict the spontaneity of a reaction.
Heat engines: These are devices that convert thermal energy into mechanical energy.
Phase transitions: This refers to changes in the physical state of a substance from solid to liquid, liquid to gas or any other phase changes.
Reaction rates: This topic involves the study of the rate at which chemical reactions occur and the factors that affect it.
Enthalpy: This measures the amount of heat involved in a chemical reaction. It is often used to calculate things like bond energies and specific heat capacities.
Hess's Law: Hess's Law is used to calculate the enthalpy change of a reaction by summing up the enthalpy changes of the intermediate steps.
Heat capacity: Heat capacity measures the amount of heat required to raise the temperature of a substance by 1 degree Celsius.
Thermochemical equations: These equations are a way to describe the enthalpy change of a chemical reaction, and they are often used in calculations involving heat and energy.
Calorimetry: Calorimetry is the measurement of heat involved in chemical reactions or physical changes.
Entropy: Entropy is a measure of the disorder and randomness of a system.
Gibb's Free Energy: Gibb's Free Energy is a measure of the amount of energy available to do work in a system at constant temperature and pressure.
Thermodynamics: This is the study of heat and energy transfer in chemical reactions, and it can be used to predict how reactions will proceed under different conditions.
