A 3.00 L flask initially contains 0.325 moles of Cl2 and 0.436 moles of H2O.  When the contents of the flask reach equilibrium, O2 is present in a concentration of 0.0350 M.  What is the equilibrium concentration of Cl2 ? 2 Cl2(g) + 2 H2O(g)  ⇌ 4 HCl(g) + O2(g)

Use the overall reaction and elementary steps 1, 2, and 3, what is the predicted rate law for the reaction described?

Use the overall reaction and elementary steps 1, 2, and 3 to answer the problem below:   Which is/are the intermediate/s in the reaction?

Which of the following is NOT an allowance typically included when determining standard time?

The Mayor of Halloween Town is using time study to evaluate how long it takes children to trick-or-treat in Halloween Town.  The Mayor started a time study data collection worksheet (in seconds).  Complete the worksheet by identifying the correct values for A, B, C, and D.  Round to the nearest 0.1 seconds.  Be sure to show your work.  A = [1] seconds (round to the nearest tenth) B = [2] seconds (round to the nearest tenth) C = [3] seconds (round to the nearest tenth) D = [4] seconds (round to the nearest tenth)   The Mayor studies a second child, Julie Jollyrancher.  She is an extremely motivated trick-or-treater.  She puts forth an excellent amount of effort, and has a fairly high level of skill.  Using the Westinghouse rating tables, what pace rating should the Mayor assign to Julie?  Since no specific elements have been identified, rate Julie Jollyrancher overall instead of each element.  Justify your answer on your scratch work, including all assumptions.  Julie’s rating should be [5]%.  (round to the nearest whole number) Remember to justify this answer on your scratch work!   The Mayor found a normal time of 64.2 seconds using the Julie’s time study. What is the standard time?  State any assumptions you used to arrive at your answer. Standard time = [6] seconds (round to the nearest tenth)

It is important that standard time be as accurate as possible.  What is one possible negative outcome of setting a standard time too long?  What is one possible negative outcome of setting a standard time too short?
