In this video, we are going to talk about how a catalyst affects different aspects of a reaction.
00:06
Specifically, we want to know what increases and what decreases and what stays the same or has no effect, which i'll just put n .a.
00:20
So we have the rate of the forward and the rate of the reverse reaction.
00:24
Now, a catalyst is going to speed up a reaction, both the forward and the reverse.
00:29
So the rate of the forward will increase and the rate of the reverse.
00:35
Reverse reaction will increase.
00:40
How does the catalyst do so? it lowers the activation energy barrier.
00:45
So that means the activation energy is going to decrease for both the forward and the reverse.
00:59
And then we have some other factors on the bottom.
01:01
So the reason that the rates are going to speed up and activation energy decreases is because the mechanism of the reaction changes.
01:12
The catalyst offers an alternate mechanism with a lower activation energy...
