The standard enthalpy of formation is the change in enthalpy when one mole of a compound is formed from its elements in their standard states under standard conditions (298 K and 1 atm). It is a crucial parameter for calculating reaction enthalpies and understanding the energy changes involved in chemical reactions.

Standard conditions refer to a set of agreed-upon reference conditions for temperature and pressure used in scientific experiments to ensure consistency and comparability of results. These conditions typically involve a temperature of 0°C (273.15 K) and a pressure of 1 atm (101.325 kPa), although variations exist depending on the field and context.

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.
