Textbook Question
Chapter 8.1, Problem 3CC
WHAT IF? → If you place a teaspoon of sugar in the bottom of a glass of water, it will dissolve completely over time. Left longer, eventually the water will disappear and the sugar crystals will reappear. Explain these observations in terms of entropy.

NaCl (s) -> NaCI (aq) is accompanied by an increase in entropy because

[Select]
a solute was dissolved in water, forming a solution
the number of products is greater than the number of reactants
the phase change from vaporization is towards a higher internal energy
The second law of thermodynamics, in a very general sense, states that entropy (S) is always increasing.

When phospholipids are dispersed in an aqueous solution, they will often form more ordered structures in the form of micelles, liposomes, or lipid bilayers. This behavior
seemingly contradicts the second law of thermodynamics. Why is this behavior in agreement with the second law of thermodynamics?
Liposome
Micelle
Bilayer sheet
kcat = ?
an enzyme has an aspartic acid in the active site with a pKa = 4.0 and the kcat for this enzyme is directly proportional to the fraction of this side chain that is ionized. If the kcat at pH = 4.0 is 52.9x103 s-1 what is the kcat for this enzymes at pH 3.5
