When you think about kinetics, one of the things you normally think about is the reaction coordinate diagram where we have energy versus the reaction coordinate or time.
00:10
And you normally have a positive activation energy that you have to overcome in order for the reaction to occur.
00:19
And if we think about a bimolecular reaction where we have two substances that are going to react together, for that reaction to take place, we have to have a collision.
00:35
It has to be a collision with a sufficient energy, that activation energy, and the molecules have to have the right orientation and space for that to be achieved.
00:45
So what we normally find is that at the beginning, we have our two pieces separated at the beginning here.
00:54
And then what happens with these two things? these two things collide and they form an activated complex, which is normally at that peak of energy that's needed, that activation energy.
01:09
And then eventually the reaction can go on and form products.
01:15
But we're talking about thermodynamics here as well.
01:19
So what happens to the entropy of this particular system is we go from point one to point two...
