Work requirement 4 is connected to the Industrial Chemistry Section and will be assessed as a portfolio of items that are completed during this area of study.

Significant amounts of the exam CAT 1 is based directly on this work requirement, consequently it is important that students have the fundamental experiences involved in and understandings derived from this task.

Some components of the Portfolio will be assessed on an ongoing basis.

If an item of the portfolio is not performed to a satisfactory standard, the item will be returned and the student will have the opportunity to redo and resubmit the item.

The work requirement will be assessed to an S or N standard.

The Work Requirement has 2 focus questions:

1. Why are certain chemicals produced in large quantities?
2. What compromises must be made in the production of these chemicals?

The folio will consist of the following items:

• Exercises: Technological, economic & environmental factors affecting chemical production
• Preparation of 3 flowcharts - for the production of iron, sulfuric acid and ethene.

• Identify significant reactions as balanced equations
• Describe the conditions under which reactions proceed, including the function of any catalysts
• Indicate the reactions for which equilibrium considerations are important
• The technological, economic and environmental considerations involved in production
• Indicate major uses of the chemical involved
• Indicate the scale of production of the chemicals
• Indicate the compromises (if any) between rate of reaction and equilibrium considerations etc

It is anticipated that this work requirement will take approximately 10 hours.

Last Date for final submission of any unmarked folio work: Friday 1^st May
