All right, so this is another problem where we're working with the concepts of delta rg, not, and k, both of which can kind of inform us on how a reaction is proceeding.
00:15
What i mean by that is which side is favored if it isn't making more product or is it staying with more reactant? and we can also determine if it's happening spontaneously.
00:25
So we're going to get down into the nitty gritty here.
00:28
We've got our reaction, which is basically the form.
00:31
Of a mole of an o gas, and then we've been given the delta rg not.
00:38
And we're going to hop down and use this handy equation.
00:43
Delta rg not equals negative r -t -l -n -k, just like that.
00:50
We have everything we need except for the k, actually.
00:56
So we're going to find this algebraically.
01:02
But first we're going to plug everything in.
01:03
So this is equal to, i'm going to write down here because we have a delta rg knot actually.
01:11
So 86 .58 equals negative 0 .00 -834 because we're working with delta rg, not just in terms of kilojoules, so we need that to match up.
01:27
We're going to assume a temperature of 298 kelvin and then natural log of whatever our kp value is, which is, which is, unknown for this problem...
