Solid substances are most likely to sublime if they
a. high or low vapor pressures?
b. weak or strong intermoleculer forces?

a. High vapor pressures

b. Weak intermolecular forces

Explanation:

a. Sublimation occurs when the vapor pressures is equal to the applied pressure in the solid. Therefore, the higher the vapor pressure, the easier it is to be equal to the external pressure and the most likely is the solid to sublime.

b. Sublimation requires intermolecular forces to be weakened in order to go from the solid state to the gas state. Therefore, the weaker the intermolecular forces, the easier sublimation will be.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
