How do you use the equation for heat flow at constant
WebJan 30, 2024 · The enthalpy change of Step 1 is the molar heat of fusion, \(\Delta H_{fus}\) and the enthalpy change of Step 2 is the molar heat of vaporization, \(\Delta H_{vap}\). Combining these two equations and … The heat of fusion can also be used to predict solubility for solids in liquids. Provided an ideal solution is obtained the mole fraction of solute at saturation is a function of the heat of fusion, the melting point of the solid and the temperature of the solution: Here, is the gas constant. For example, the solubility of paracetamol in water at 298 K is predicted to be: the miracle tony davis
