So to solve for this, let's write the equation.
00:06
Delta g is equivalent to the negative rt, ln of k.
00:10
So our unknown here is k.
00:12
So rearranging this equation, we'll have ln of k.
00:16
It's equivalent to delta g over negative rt.
00:20
Okay, so for the first given, let's substitute it right here.
00:25
Delta g is said to be 10 .5 kilojoules per mold.
00:30
And let's convert this to joules.
00:33
We have one kilojoules equivalent to a thousand joules.
00:36
So we converted this to joules because our r is in terms of joules.
00:41
And then we have negative r, which is 8 .314 joules per mole kelvin.
00:48
Multipled by the temperature, which is equivalent to 298 kelvin.
00:53
So as you can see, we could cancel some units.
00:55
Kilojoules, j, j, jos, and kelvin.
01:00
And also moles.
01:01
So as you can see, k will be unitless.
01:05
So ln of k is equivalent to negative 4 .238, and that means to remove ln will raise this to the power of e...
