00:01
The equilibrium is phosgene, producing carbon monoxide and chlorine gas.
00:06
K, p, will be equal to the pressure of carbon monoxide multiplied by the pressure of chlorine divided by the pressure of fosgene.
00:14
They tell us this value is 7 .2 times 10 to negative 2.
00:18
They give us information associated with fosgene that we can use to calculate with the ideal gas law, the initial pressure of fosgene.
00:27
We'll take the mass divided by the molar mass of phosgene to get moles, moles multiplied by r and t, the kelvin temperature, 300 degrees celsius is 573 kelvin, and then we divide by the volume.
00:43
This gives us an initial pressure of 0 .324 atmospheres fosgene.
00:50
Then, according to the stoichiometry, the reaction will shift to the right to establish equilibrium, decreasing phosgene by x...
