28. The autoionization of water, \( \text{H}_2\text{O}(l) + \text{H}_2\text{O}(l) \rightleftharpoons \text{H}_3\text{O}^+(aq) + \text{OH}^-(aq) \), is known to be endothermic. Which of the following correctly states what occurs as the temperature of water is raised? (A) The pH of the water does not change, and the water remains neutral. (B) The pH of the water decreases, and the water becomes more acidic. (C) The pH of the water increases, and the water remains neutral. (D) The pH of the water decreases, and the water remains neutral.

25. Initial rate data have been determined at a certain temperature for the gaseous reaction 2NO + 2H₂ <=> N₂ + 2H₂O

What is the rate law?
(A) Rate = k[NO][H₂]
(B) Rate = k[NO][H₂]²
(C) Rate = k[NO]²[H₂]
