Determine whether the equilibrium concentration of HI g will be greater than,. For the reaction represented above, the value of the equilibrium constant, K p , is 3. K if the initial partial pressures are. Visit apcentral. The gas-phase conversion reaction between the geometric isomers cisbutene and transbutene is represented.

The value of the equilibrium constant, K eq , for the reaction is 3. Draw one of these isomers, including. Be sure to write all your answers to the questions on the lined pages following each question in the goldenrod. Answer Questions 1, 2, and 3. The Section II score weighting for each question is 20 percent.

A sample of solid U 3 O 8 is placed in a rigid 1. Chlorine gas, Cl 2 g , is added, and the flask is heated. The equation for the reaction that takes place and the equilibrium-constant expression for the reaction. When the system is at equilibrium, the partial pressure of Cl 2 g is 1. Does the mass of. Solid carbon and carbon dioxide gas at 1, K were placed in a rigid 2.

As the reaction proceeded, the total pressure in the container was monitored. When equilibrium was reached, there was still some C s remaining in the container. Results are recorded. Assume that the volume of the. Justify your answer. Assume that the volume of the solid catalyst is negligible.

In another experiment involving the same reaction, a rigid 2. Answer the following questions regarding the decomposition of arsenic pentafluoride, AsF 5 g. The compound butane, C 4 H 10 , occurs in two isomeric forms, n-butane and isobutane 2-methyl propane. Clearly label each structure. Justify your. In part b only two points were earned, one for explaining that biorhythm is a hormone-caused response to change in light in animals, without explaining how this happens, and one for explaining that a hormone causes the reabsorption of water in animals, without explaining what response this produces.

In part c no points were earned. Sample 2C 10 points This essay received all four points in part a , one for identifying stem elongation as a hormone-caused response that accounts for increased height in plants , one for explaining how a hormone causes the response; one for identifying flowering as a hormone-caused response to change in light and one for explaining how a hormone causes the response.

In part b all four points were earned, one for identifying concentration of urine as a hormonecaused adjustment to lack of water in animals, one for explaining how a hormone causes the response; one for identifying bone growth as a hormone-caused response that accounts for increased height in animals , one for explaining how a hormone causes the response.

In part c all four points were earned, two for explaining that hormones which enter cells bind to receptors in the cell and influence transcription; two for explaining that hormones bound to cell membranes activate proteins via signal transduction.

Question 3 Sample 3A 4 points In part A, the student was awarded 2 points for describing the property of cohesion and correctly linking it to the movement of water through the xylem vessels, as part of the transpiration process.

This student also received 2 points for correctly describing the structure of the plasma membrane and clearly indicating how water influences this structure. No points were awarded in parts B or C. In part B, the student incorrectly described the role of water as a product in the carbon cycle. The student failed to establish a clear link to the water cycle so no point was awarded.

Such attempts were typical in many student responses. In part B, the student was awarded 2 points for correctly linking an accurate description of membrane structure to the influence that surrounding water molecules have on the membrane itself.

In part B, 2 points were awarded for correctly identifying water as being a reactant in photosynthesis and a product in cell respiration. Sample 3C, 10 points In part A, 2 points were awarded for correctly linking the cohesion of water molecules to the process of transpiration. In part B, the student was awarded 2 points for correctly identifying water as both a reactant in photosynthesis and a product in cellular respiration.

This student also received 2 elaboration points for correctly describing the specific role of water in each of those processes.

In Part C, 4 points are present but only 2 were awarded as the student had reached the maximum of 10 points. The student received 2 points for correctly identifying the cause of global warming and predicting that this warming would lead to increased evaporation, thus influencing the water cycle.

Additional points could also have been awarded for predicting that global warming would lead to the increased melt of polar ice caps and linking that to an increase in sea level. Sample 4B 6 points The student got in order the explanation point, the definition point, and the example point for mutation; the definition point and the explanation point for population bottlenecks; and the explanation point for the growth of human populations.

Sample 4C. For the growth of human population selection it got the definition point and the impact point.
