Let's say we have a leonard jones potential that has to form 4 epsilon times sigma over r to the 12th power minus sigma over r to the 6th power.
00:16
And we're told that, let's see, sigma is 2 .63 times 10 to the negative 10 meters.
00:26
And epsilon here is 1 .51 times 10 to the negative 22nd joules.
00:34
So we want to plot this as a function of x, which is pretty straightforward.
00:40
It's a very famous potential energy function.
00:44
So u of r versus r kind of looks like this, i suppose, or kind of you redraw it.
00:57
Kind of looks like this.
01:01
And then we also want to find the most likely distance between the atoms.
01:06
So we'll consider that part a.
01:08
So this occurs when the potential energy is zero...
