31.   Approximate measurements of the enthalpy change for reactions in solution can be made using a simple calorimeter such as a polystyrene beaker.

32.   You will notice that the entropy change for this reaction is negative.

33.   Should not the entropy change for the reaction therefore be positive-as required by the second law of thermodynamics?

34.   In conclusion, although the enthalpy change for the reaction system is negative, the total entropy change which accompanies the reaction is positive.
