Thermochemistry is a branch of chemistry that studies the relationship between heat and chemical reactions. It focuses on the energy changes that occur during chemical reactions and how these changes can be measured and utilized.
Thermochemistry is a subset of thermodynamics, which is the study of energy and its transformation. While thermodynamics deals with all forms of energy, thermochemistry specifically focuses on the heat energy involved in chemical reactions.
Enthalpy is the total energy of a system, including both its internal energy and the energy associated with its surroundings. It can be measured experimentally using a calorimeter, which measures the heat exchanged during a chemical reaction.
Temperature has a direct impact on the rate of a chemical reaction. As temperature increases, the particles in the reaction have more energy and move faster, leading to more frequent and energetic collisions. This results in a faster reaction rate.
An exothermic reaction is a chemical reaction that releases heat energy into its surrounding environment. An example of an exothermic reaction is the combustion of propane gas, which produces heat energy and releases carbon dioxide and water as byproducts.
