So this problem gives us the chemical equation co gas plus h2o gas reversibly reacts to form co2 gas plus h2 gas.
00:18
And then gives us a kp of 0 .0611 at 2 ,000 kelvin.
00:27
And so the first thing we want to do is an ice table, initial change equilibrium.
00:32
So we're given the initial pressure of co is 1344 tor, and the initial pressure of h2o is 1766.
00:41
And then we assume that the initial pressures here are zero.
00:46
Our change is minus x for our reactants and plus x for our products.
00:53
And so our equilibriums are just adding down the columns.
00:57
So 1344 minus x, 1766 minus x, and then for our products, just each of them is x.
01:07
So now we can set up our kp equation.
01:11
Kp is equal to the partial pressure of the product co2 times the partial pressure of the product h2 over the partial pressure of the product co times the partial pressure of the product h2o.
01:27
And that equals 0 .0611.
01:31
And now we know what these values are...
