Looks like I missed a couple days...
Since the last exam, we've been looking at Kinetics and trying to understand rates of chemical reactions. That has included average rates over (relatively) long time periods, and rate laws which describe the instantaneous initial rate of a reaction. By doing a little calculus, rate law expressions can be converted to integrated rate laws which show the relationship between concentration and time. Today we got to the idea of activation energy and looked at an example of a reaction that doesn't occur until a spark is added. Activation energy is found by using the Arrhenius equation in one of its forms ("standard", comparative or linear).
The new Mastering Chemistry Assignment is posted, due Monday. There will be another MC assignment posted on Friday, so don't wait to get started on this one...
