25. The standard molar free energies of formation (△G) of NO2(g) and N2O4(g) at25 °C are 52 and 97 kJ/mol, respectively. Consider the equilibrium at 25 °С:2 NO2(g)⇌ N2O4(g) Which of the following statements is correct? (A) The reaction is endothermic at 25 °C. (B) △S° for this reaction is positive at 25 °C. (C) The equilibrium constant (K) is less than 1 at 25 °C. (D) Decreasing the temperature increases the ratio [N2O4]/[NO2]. (E) The reaction is spontaneous at all temperatures.

26. The rate law for the reaction 2 H2(g) + 2 NO(g) →2 H2O(g) +N2(g) is rate = H2]a[NO]β, and the rates of the reaction under different conditions are as followWhich of the following statements is correct? (A) T2 <T1 (B) α = 2, β = 1 (C) When all other conditions are held constant and only the concentrations of the four substances in the reaction system are varied, only the change in the concentration of the reactants has an effect on rate, and the effect of [NO] is greater. (D) At T2, [NO] = 0.1 mol·L-1, the reaction rate is 8r, then [H2] =0.3 mol·L-1 (E) According to the varied reaction rates above, this is an endothermic reaction.
