Substituting this equation and the definition of internal energy at constant pressure (ΔE = qp + w) into the enthalpy-change equation yields:where qp is the heat of reaction under conditions of constant pressure. And so, if a chemical or physical process is carried out at constant pressure ...
74K When energy is transferred during a chemical reaction, it is called enthalpy. Examine the changes that happen, the relationship to energy, heat, and temperature, exothermic and endothermic processes, and physical and chemical changes during enthalpy. Related...

In symbols, the enthalpy, H, equals the sum of the internal energy, E, and the product of the pressure, P, and volume, V, of the system: H = E + PV. The Heat of Reaction (also known as enthalpy of Reaction) is the change in the Enthalpy of a chemical reaction that occurs ...
