4. At high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why?
It is much greater because real gas particles take up space.
There is no difference because the gas laws are always obeyed.
It is much less because real gas particles are not moving.
It is much less because at high pressures the temperature drops.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
