IB Chemistry: Entropy & spontaneity questions

1. Given that the standard entropy of gaseous water is 189 J K-1 mol-1and the standard entropy of liquid water is 69.9 J K-1 mol-1 calculate the standard entropy change when one mol of gaseous water condenses to the liquid state, H2O(g) → H2O(l).2. (a) Predict the sign (positive or negative) for the entropy change for the reaction:2NO2(g) → N2O4(g)(b) Explain why the entropy change for the above reaction is considerably...
