CHEM ENG 3034 - Kinetics and Reactor Design
North Terrace Campus - Semester 1 - 2020
General Course Information
Course Code CHEM ENG 3034 Course Kinetics and Reactor Design Coordinating Unit School of Chemical Engineering Term Semester 1 Level Undergraduate Location/s North Terrace Campus Units 3 Contact Up to 4 hours per week Available for Study Abroad and Exchange Y Incompatible CHEM 3017 Course Description This course aims to establish fundamental knowledge of reaction engineering and kinetics for students in chemical engineering and pharmaceutical engineering. Chemical reactions occur in different phases including the gas phase, in solutions with different solvents, between interfaces including gas-solid and liquid-solid, and other interfaces in solid and liquid states. Presentation of the course starts by introducing the chemical reaction engineering algorithm and then utilises it to solve problems in both steady and unsteady state isothermal and nonisothermal reactors. Collection and analysis of reaction rate data, complex mechanisms and bioreactors are also discussed. At the end of the course catalysis is introduced as well as the effects of combined diffusion and reactions on catalyst particles.
Course Coordinator: Dr Philip van Eyk

Catalyst poisoning.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

This assessment breakdown complies with the University's Assessment for Coursework Programs Policy.
Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.
To support the changes to teaching, the following revisions to assessment have been made:-
Quizzes: these will remain online quizzes based on the theory content. The percentage these are worth will increase to 10% of the final grade.
Tutorials: these will remain the same written solutions to problems posed each week. The percentage these are worth will stay at 20% of the final grade.
Mid Semester Test: this will be a timed online test in Week 7 of the course and will cover the first half of the content. Because it is
online it will necessitate it being Open book. You will be required to submit attachments for working as well as some spreadsheets using Excel. Methods are currently being developed to ensure it is your own individual work. The percentage this will be worth will go to 20% of the final grade.
Final Exam: this will be a timed online exam in the exam period and will cover the whole course content. Because it is online it will
necessitate it being Open book. Similar to the Mid-Semester Test, you will be required to submit attachments for working as well as some spreadsheets using Excel. Methods are currently being developed to ensure it is your own individual work. The percentage this will be worth will reduce to 50% of the final grade to account for the different style of exam than conventional exams.

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
