Last unit we talked about how increasing pressure would push the equilibrium towards the side with less moles or more compact molecules, thus creating more solids in some cases. I was wondering in cases which two gases go straight to a solid how it bypasses the step of turning into a liquid, like water does.
I suppose it would be able to bypass the step of turning into a liquid because of incredibly strong intermolecular forces, however I do not know if this would create solid materials or incredibly viscous non-newtonian-like fluids
In response to the question about dry ice, it is special in the way that carbon in the form of dry ice goes directly to a gas phase and doesn't become a liquid. Sublimation occurs because the phase change happens at temperatures and pressures that can't allow the compound to be liquid. It requires a lot of energy in the form of heat to skip the liquid phase.
It will bypass the liquid state if there is not enough pressure for the compound to form a liquid state, and thus will skip directly to the gas phase. For there to be a liquid state, the pressure would have to be very high.
