Announcements (previous ones)
- Assignment 5 (updated on 27 November) is posted.
- All 4 questions are now posted for this assignment.
- Question 3.3, part (c), the solvent flow of 15kg/hr is impossibly low. Use a revised value of 27.5 kg/hr.
- Please note that in question 1 it is not acceptable to use the Lineweaver-Burk plot method to calculate the isotherm parameters. See the course notes for a better method: the Eadie-Hofstee method.
- Note the ternary diagrams in question 2 and 3 are different.
- You may scan in your diagrams (make sure the resolution is of good quality) and submit electronically.
- The midterms are available for pickup in class or from my office. Grades are now posted to Avenue. I've had a chance to analyze the data:
- The average grade for the midterm was 71.2 (median was 72) with a stdev of 13.9, which is a little higher than I prefer. The distribution is mostly normal, with a slightly heavy left tail. There is nothing in the grades to warrant adjustment (i.e. "curving").
- Assignment 5 has sufficient bonus grades to boost your grade; in addition to the take-home exam that's been dropped and course grades redistributed.
- As mentioned in class, I apologize for the delay in grading. Overhauling this course while teaching it for the first time, and teaching 4N4 for the first time has just used up all my spare hours.
- For issues regarding the midterm grading, please see Kevin regarding questions 3, 4, 7, 8, 9, and see Daryl for the others.
- Some of you might be confused by the modified grading for the course. Here's a spreadsheet to plug in your grades and see what happens.
- Could I please ask you all to seriously consider filling in a course evaluation at https://evals.mcmaster.ca - they are really helpful for me to update and shape the course for 2013. Evaluations close on 04 December.
