What is the significance of the equilibrium constant? What does a large equilibrium constant tell us about a reaction? A small one? Match the words in the left column to the appropriate blanks in the sentences on the right. ResetHelp reverse concentrations masses reactants products forward The equilibrium constant for a reaction is the ratio-at equilibrium-of the Blank of the Blank raised to their stoichiometric coefficients divided by the Blank of the Blank raised to their stoichiometric coefficients.target 1 of 6target 2 of 6target 3 of 6target 4 of 6 If the equilibrium constant for a reaction is large (K≫1K≫1), the Blank reaction is favored.target 5 of 6 A small (K≪1K≪1) equilibrium constant for a reaction indicates that the Blank reaction is favored.

Consider the parametric curve: $x = 81 - t^2$ $y = t^3 - 4t$ At which $t$ value(s) is the tangent to this curve vertical? (Note: If there is more than one write them as a comma separated list) t = 0 Write the point(s) at which the tangent is vertical. (Note: If there is more than one write them as a comma separated list, e.g. (1,2), (3,4)) (81,0) At which $t$ value(s) is the tangent to this curve horizontal? (Note: If there is more than one write them as a comma separated list). t = Write the point(s) at which the tangent is horizontal. (Note: If there is more than one write them as a comma separated list, e.g. (1,2), (3,4)) Use a graphing device to graph the curve and check your work.

5. The recommended daily dietary allowance (RDA) for zinc among males older than 50 years is 15 mg/day. An article based on this study reported the following data on zinc intake for a sample of males age 65-74 years: n=20, $\bar{x}$ = 7.3, s=2.43. With a significance level of 0.01, does this data suggest that $\mu$, the average daily zinc intake for the entire population of males age 65-74, is less than the RDA?

A 51-year-old has picked up cycling as a hobby. He is 6'1" tall and weighs 195 pounds. You have him cycling on a Monark cycling ergometer (6 meters per revolution). If you started at 60 rpm with 3 kg of resistance and added 0.5 kg every 3 minutes while he maintains 60 rpm, and he failed after 12 minutes and 5 seconds. What would you predict his VO2max to be? 29.9 ml/kg/min 31.3 ml/kg/min 36.4 ml/kg/min 39.9 ml/kg/min
