Question 1

A reaction has ΔH° = -60.9 kJ/mol and ΔS° = 266.6 J/K. Is this reaction spontaneous or nonspontaneous? At what temperature (if any) can the spontaneity be reversed?
◦ spontaneous, cannot be made nonspontaneous at any temperature
◦ nonspontaneous, can be made spontaneous at 228 K
◦ nonspontaneous, cannot be made spontaneous at any temperature
◦ spontaneous, can be made nonspontaneous at 228 K

Question 2

Calculate the standard free energy change at 25°C for the reaction

2 NO(g) + O2(g) → 2 NO2(g).



◦ -72.6 kJ
◦ -157.8 kJ
◦ -532.6 kJ
◦ -4.7 kJ

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
