Interpretation:
Estimation of heat effect when LiCl is added to an aqueous solution in an isothermal process at 298.15 K.
Concept introduction:
When chemical reaction takes place at same and P then due to chemical rearrangement of atoms the energy of reactants are different than products. Similarly, when a mixture is formed due to the attraction or repulsion of, like or unlike atoms energy change occurs which is less than energy due to chemical bonds. The heat of mixing is generally less than the heat of reaction and can be written as follows:
Where,
H = enthalpy of pure species at T and P.
