Which of the following descriptions and/or equations best represent the enthalpy change of a system? There may be more than one correct answer.Choose one or more:A. The sum of the internal energy and the pressure-volume product of a system B. The heat absorbed or released during a phase change or chemical reaction at constant volume C. The heat absorbed or released during a phase change or chemical reaction at constant pressure D. The amount of energy required to raise the temperature of 1 mole of a substance by 1°C at constant pressure E. ΔH = ΔE + PΔVF. H = E + PVG. ΔE = q + wH. The work done on or by a phase change or chemical reaction at constant pressure F. H = E + PVG. ΔE = q + wH. The work done on or by a phase change or chemical reaction at constant pressure
