Recall that in order to get a value for k -e -q from delta -g, we use the equation k -e -q is equal to e -k -to -the -negative delta -g divided by r -t.
00:32
So let's use this equation to plug in some values so that we can compare the k -e -q for reactions a, b, and c.
00:51
And in this case, r is a constant, which is 0 .008 -3 -1 -4.
01:02
And the unit for that is going to be kilojoules per mole -calvin and let's assume that the temperature is going to be equal to 298 kelvin just to keep things consistent.
01:31
So let's plug in to the equation using the delta gs we were given.
01:39
So in the first one, delta g is positive 24 kilojoules.
01:55
And then i'm not going to write the units for this because it might get a little messy.
02:00
But 8, 3, 1, 4, this is going to be our r times 298, which is kelvin.
02:19
And we'll get approximately 6 .2 times 10.
02:27
To the minus 5.
02:31
Moving on to b, k -e -q will be equal to e to the negative.
02:43
The value for delta g is positive 4 .4.
02:47
So we'll put it in 4 .4.
02:51
Divide that by .00834 times 290...
