PPT-Entropy changes of pure substances: retrieving data from pr

Tds relations relate properties of any pure substance exactly to entropy change But it is not convenient to use them Instead tabulated data for s are used eg Table B1 for water Table B5 for refrigerant R134a. 1 The entropy of a pure crystal at Absolute Zero = 0 Why? Because all forms of molecular motion stop at absolute zero, so there can be no entropy content. Predicting Reaction Spontaneity: Gibbs Fre : Session 1. Pushpak Bhattacharyya. Scribed by . Aditya.
