(A) Predict whether the change in entropy (ΔS) is positive, negative or near zero for the following processes at 298K. Provide a molecular level explanation or justification for your prediction.
(B) Calculate the change in entropy (ΔS) for the following processes at 298K.
i. H2O (s) → H2O (l), melting of ice.
ii. Formation reaction for steam (water vapor, H2O (g)).
iii. C3H8 (l) → C3H8 (aq), Liquid propane going to aqueous propane.
iv. The hydrolysis of the dipeptide glycylglycine
