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 ...
Forum:Chemistry A Energy of products in endothermic reaction How is the energy of products in endothermic reaction more than the energy of reactants When we see the following equation of an endothermic reaction below 2H2O2--> 2H2O + O2 The 2H2O2 has an enthalpy of 2144 whereas the product...
