Our goal is to find delta rg not from starting with just a value of k and a temperature from a given reaction.
00:08
We're going to talk about the dissolution of acetic acid at 25 degrees celsius.
00:13
And the ionization constant, ka, is 1 .8 times 10 to the negative 5th.
00:19
And real quick before we start, we're going to just convert our celsius temperature into kelvin by adding 273.
00:27
So this is going to be 298 kelvin.
00:30
And the equation that's going to relate all this is going to be delta rg not equals negative r -t -l -n -k.
00:42
It's going to be one of our consistent equations we're going to use to relate the equilibrium constant with the delta -r -g -0.
00:49
So again, we're trying to find this.
00:51
We've got everything else we need, actually.
00:54
So we can fill in what we know...
