Consider the following system: H2(g) + I2(g) H 2HI(g) A quantity of pure HI (hydrogen iodide) was placed in an empty vessel at 731 K and the system was allowed to come to equilibrium. An increase in the reaction vessel would: cause the reaction to proceed to completion. cause the production of more H2. cause the production of more HI. cause no effect on the equilibrium. Question 3 The equilibrium constant for a chemical reaction can be changed by: O increasing the temperature. adding a catalyst. O increasing the concentration of the products. O increasing the concentration of the reactants OOOO

1-11 Exactly 5.00-mL aliquots of a solution containing phenobarbital were measured into 50.00-mL volumetric flasks and made basic with KOH. The following volumes of a standard solution of phenobarbital containing 2.000 µg/mL of phenobarbital were then introduced into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50, and 2.00 mL. The fluorescence of each of these solutions was measured with a fluorometer, which gave values of 3.26, 4.80, 6.41, 8.02, and 9.56, respectively. (a) Plot the data. *(b) Using the plot from (a), calculate the concentration of phenobarbital in the unknown.

11 of 11 I Review | Constants Periodic Table Suppose that you want to construct a line with slope m = 3 that passes through the point (2, 1). You would begin by setting up the equation y = 3x +b If you plug in the coordinates for any point on that line, the two sides of the equation will be equal. Once you've done this, you can solve for b. What is the value of b? Express your answer as an integer. > View Available Hint(s) 8:59 PM 41% 67°F x口ツ 8/31/2021
For questions #14-16, you should do your work on a separate piece of paper and then upload it. You should use the GUESS Method of solving for each problem. Also, you have a choice. You can complete both #14 & #15 which are single step question or do the extension problem which is a 2 step problem instead of 14 & 15. You must complete #16.
