22. Consider the following reaction at 25°C: 2NO2(g)⇌N2O4(g). The values of ∆Ηο and ∆Sο are -58.03 kJ/mol and -176.6 J/K•mol, respectively. Assuming ∆Ηο and ∆Sο are temperature independent, estimate the value of K at 100.0°C. (A) 3.00 × 106 (B)(C) 8.72 (D) (E)

25. When proteins in solution are heated, the hydrogen bonds in proteins may be broken to result in collapsing of protein secondary structures. What will be the effects of the heating process on ∆H and ∆S of the proteins? (A) ∆H and ∆S all will increase. (B) ∆H and ∆S all will decrease. (C) ∆H will increase but ∆S will decrease. (D) ∆H will decrease but ∆S will increase (E) Both ∆H and ∆S will not change.
