Activated Complex Model

On Outline 6, one of the bulletpoints states 'Explain how the collision model and activated complex model account for the temperature dependence of reactions'. I was wondering if someone could clarify what the activated complex model is and how it accounts for the temperature dependence of reactions?

Re: Second Discussion Test

Test 2 will be during your Week 8 discussion and I believe it will cover whatever is taught from after the midterm up to the end of Week 7.

Re: HW this week

I think we are still in the Chemical Bonding, so I am doing problems from that section, but I'm sure you won't lose points for doing hw from the next section!

Re: What is the Octet Rule?

The Octet Rule states that elements usually bond so that each atom has a full electron shell (which is 8 electrons). This happens because atoms with a full electron shell are the most stable. Hope this helped!

Re: Study For midterm

I have been doing all of the assigned homework problems instead of just 5 to get a lot of practice with different types of problems that could potentially be on the midterm. Going to step-up sessions and workshops are also very helpful. Hope this was helpful and good luck studying!

Re: Stable Structures

Yes a structure is most stable when its formal charge is 0! However this is not always possible, so the closer a formal charge is to 0 the more stable it is.

Re: Theoretical vs. Actual Yield

Actual yields will be less than theoretical yields due to side reactions that can occur, some products could stick to the sides of the reaction container, and impurities that are bound to happen during almost all chemical reactions. Hope this was helpful/answered your question!
