The Reaction of Gas Phase Carbon Monoxide Questions

Value: 10% of your final grade

  1. Write your student number on each page of your assignment.
  2. You must submit your assignment to Gradescope as a .pdf. Please review the instructions for how to submit an a .pdf assignment. There are also instructions on MyLS for how to convert images to a .pdf if you need to do so.

You should answer questions using the formatting that has been provided. There several ways that you could do this:

  1. You can print the assignment, complete it on paper, and then follow the instructions in the Gradescope folder on MyLS to take a picture, save as a .pdf, and upload to Gradescope.
  2. You could do your work on paper, take a picture, and insert the image in the Word document. You can save this document as a .pdf and upload to Gradescope.
  3. You could do all your work on your own paper (no printer), and then follow the instructions in the Gradescope folder on MyLS to take a picture, save as a .pdf, and upload to Gradescope.
  4. Students with tablets may want to fill out this document on their device, convert it to .pdf, and upload to Gradescope.
  5. You must show full work (include units) for your problems.
  6. You are permitted to use your textbook and other course resources (MyLS) and to talk to your classmates about this assignment, but your submission must be your own individual work. You should not copy the work of others. You should not share your work with others. You should not accept help from others who want to send you their work.
  7. You are required to sign the Academic Integrity Pledge at the end of the assignment.

Academic Integrity

It is expected that all students will follow assignment instructions and will adhere to Laurier’s regulations with respect to Academic Integrity.

The following violate Laurier’s Academic Code of Conduct:

  1. Posting assignment questions to message boards, social media, or other unauthorized websites (ex. Reddit and Chegg). These questions are the intellectual property of your course instructor, and you do not have permission to share them outside those registered in our class.
  2. Posting assignment answers in virtual “course groups” (ex. Facebook, Discord or WhatsApp). While you can discuss problem solving strategies, it is expected that you will carry-out the problem solving independently.
  3. Sending your work to other students. You are not permitted to send your assignment solutions to another student. Your course instructor understands that you might be doing this with the intention of helping a classmate, but this kind of “help” directly violates Section 4.01 of Laurier’s Academic Code of Conduct: misconduct is an act by a student, or by students working on a team project, which may result in a false evaluation of the student(s), or which represents an attempt to unfairly gain an academic advantage, where the student either knew or ought reasonably to have known that it was misconduct.

Your course instructor takes academic integrity seriously (because in science, it can have serious consequences for many people). If you have questions about how to conduct yourself when completing course assessments, you should contact your course instructor for guidance.

Late Policy

This assignment is due on November 15, 2020 at 11:59 pm in the folder on Gradescope that corresponds to your version of the assignment.

Assignments submitted during each subsequent hour after the due date/time will be subjected to a 10% late penalty.

For example, if you submit your assignment at 12:03am on Nov. 16, the highest grade that you will be able to achieve on this assignment is 90%. If you submit your assignment at 1:03am, the highest grade that you will be able to achieve on this assignment is 80%.

At 9:00 am on Nov. 16 your assignment will be worth 0% and will no longer be accepted.

Do not wait until 11:59 pm on Nov. 16 to submit your assignment.

Specific Assignment Instructions:

  1. Your student number has nine digits: 123456789. Replace the numbers that are bolded and highlighted in yellow with the corresponding value from your student number. For example, if your student number is 009820864, then:

0.123 mol/L = 0.009 mol/L (this means that 1, 2 and 3 refer to the 1st, 2nd, and 3rd digits in your student number)

0.456 mol/L = 0.820 mol/L (this means that 4, 5 and 6 refer to the 4th, 5th, and 6th digits in your student number)

7.89 x 102 mL = 8.64 x 102 mL (this means that 7, 8 and 9 refer to the 7th, 8th, and 9th digits in your student


If you do not understand this instruction, email your instructor with your student number and the version of your assignment, and your course instructor with clarify these requirements.

  1. For Q1, you are expected to identify at least four problem solving strategies used in arriving at your answer. The in-class problems from September 18 can be used as an example. You are not required to do this for the other questions.
  2. For Q1 you are required to identify a relevant course learning outcome. These can be found at the end of your syllabus. Please do not make up your own learning outcomes. You are not required to do this for the other questions.
  3. At the end of your assignment, you must rewrite and sign the Academic Integrity Pledge.

Q1) Carbon dioxide can be synthesized in the gas phase by the reaction of gas phase carbon monoxide with gas phase oxygen. A 10.0 L reaction flask contains carbon monoxide gas at 0.461 bar and 22.0 °C. 123 mL of oxygen gas at 7.89 bar and 271 K is introduced. Assume the reaction goes to completion (100% yield).

  1. Write the balanced reaction. Include phases.
  2. What are the partial pressures of each gas at the end of the reaction, once the temperature has returned to 22.0 °C? Express your final answer(s) in units of bar.
