20. A. B. C. D. E. 21. A. B. C. D. E. 22. A. B. C. D. E. Consider the following reaction at equilibrium at 339 K: C₂D₂(g) = 2C(g) + D₂(g) If the same reaction was conducted at 542 K and the new equilibrium constant was found to be 2.5 times that of the value of Ke, this would imply that: the forward reaction is exothermic ..K₂ = 0.00112 an equilibrium constant is inversely proportional to temperature the reverse reaction is endothermic an equilibrium constant is directly proportional to temperature the forward reaction is endothermic What occurs when a 35 gram aluminium cube at 100°C is placed in 90 grams of water at 25°C? Heat is transferred from the aluminium to the water, and the temperature of the water increases Heat is transferred from the aluminium to the water, and the temperature of the water decreases Heat is transferred from the water to the aluminium, and the temperature of the water decreases Heat is transferred from the water to the aluminium, and the temperature of the water increases None of the above. The pH of a solution made by dissolving 522 mg of potassium hydrogen phthalate (KHCBH4O4) in water and diluting to a total volume of 250 cm³ is 4.24. The K₂ for the phthalate ion (HC8H4O4) is: 5.66 x 10-³ 5.75 x 10-5 1.02 x 10-² 2.54 x 10-2 3.26 x 107
