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 pressur...
Enthalpy: Definition and Derivation You already know that heat absorbed or released by a body is related to its internal energy. The heat absorbed is equal to the change in the internal energy. This is given by ∆U = qV. But this equation holds good only at a constant volume. However,...
the bonds between atoms can dissolve, reform or both during chemical reactions to either absorb or release energy. the heat absorbed or emitted under constant pressure from a device is referred to as enthalpy, and the reaction enthalpy is the change in enthalpy arising from a chemical reaction....
