Conclusion: selection of technology for further development)
This Design Project is to design a process plant for the production of acetic acid as defined in the Design Intent. In this first assessment, all students are required to prepare an individual report to review the possible process routes for acetic acid on the basis of their technical, safety, environmental and economic viability.
The marking criteria is defined in detail in the attached rubric. Attributes assessed in the marking rubric include:
➢ Possible process routes for the production of acetic acid
➢ Consideration of safety, environment and sustainability for each process route
➢ Possible technical and commercial applications of acetic acid, including market demand
➢ A cost estimation for acetic acid production
➢ A Net Present Value calculation for acetic acid production
In Trimester one, you will be required to produce a feasibility report on a process route for the production of acetic acid. This should address the following issues:
* Is the chosen route technically viable?
* Is the chosen route environmentally viable?
* Is the chosen route economically viable?
Submission of a Feasibility report consisting of the technical, environmental and the economic viability of the chosen process route for the production of acetic acid. The details of assignment one can be found .

follow the lab report format. No post/pre lab.
Comments from Customer
I’m not sure what the previous writer caused but I only took that pic. Also the their was no graph or data. Everything that was in procedure steps (shown in procedure steps on the chalk board ) we followed. Some parts we didn’t follow in the lab manual. Mostly based on the revised procedure steps.

As you learn to view the world through a chemistry lens, it will become importan

As you learn to view the world through a chemistry lens, it will become important for you to learn to use the language of chemistry. There are some challenges associated with chemistry vocabulary because many of the words that are used in a technical sense in chemistry might also be used in everyday language. However, the meanings of the words in the two contexts can be very different. In the discussion questions for this course, we will practice using these terms and becoming comfortable with going back and forth between their everyday and technical meanings. This week, consider the following terms:
•Element
•Compound
•Molecule
•Density
•Precision
•Accuracy
Respond to the following in a minimum of 175 words and also leave two comments of 50 words each separated :
Choose at least 2 terms from the list, and answer the following questions for each term:
What familiarity and prior knowledge do you have about the term?
What does the term mean in everyday language to everyday people? Use examples to help describe your thoughts. How do people use the word?
What does the term mean in technical language to chemists?
How is the term related to the course student learning outcome: Explain matter at the microscopic level?
What are the similarities and differences between the everyday and technical meanings and uses of the term?
What impact might the similarities and differences have on your learning of chemistry concepts in this course?
