In there, when we are talking about an equilibrium, we see the word equal.
00:10
Well, what is equal in an equilibrium? it's the forward and reverse process are equal.
00:28
In other words, they occur at the same rate.
00:40
Therefore, the amount of each substance does not change.
00:50
The amount of each substance is not necessarily equal.
00:53
In fact, rarely is it equal, but the amount of each does not change once we are at equilibrium.
01:09
So this could be a chemical reaction where the amount of each type of reactant remains constant and the amount of each type of product remains constant.
01:19
Or it could be a physical relationship where we have evaporation and condensation going on at the same rate, or perhaps freezing and melting going on at the same rate.
01:29
Those would all be examples of equilibriums.
01:36
All right, so even though these are at equilibrium, where the word dynamic comes in, that means it's not static because the forward and reverse processes are still happening.
02:14
So even though the reaction seems to be sitting still, it appears that nothing's happening.
02:22
It is still happening.
02:23
The forward and reverse process is still occurring...
