Hi there.
00:03
In this question, we are looking at the idea of collision theory.
00:11
Collision theory says a few different things.
00:15
First of all, it says that for two reactants to react, so all of these are going to apply to a reaction.
00:23
So let's back up a second.
00:24
So for a reaction, we must have a collision.
00:35
So two reactants must collide.
00:45
They can't react if they're in separate containers, for example.
00:47
That would be the best example of them not colliding, colliding, is that they're in separate containers.
00:52
But even if they're in the same container, they have to collide to react.
00:56
The other thing is that they must collide with enough energy.
01:15
And that energy is used to break bonds and start the reaction.
01:18
This is, of course, called the activation energy.
01:26
And the third thing about the collision theory is they must collide in the correct orientation.
01:44
So in the simulation, two reactants colliding, and they told us to make sure that when we made them collide, that there was enough energy, there was more energy, more total energy, than the transition state...
