Le-Chatelier’s principle : If a system at equilbrium is subjected to a change of any one of the factors such as concentration, pressure or temperature, the system adjusts itself in such a way as to “Nullify” the effect of that change.
If a system in equilibrium consists of gases, then the concentrations of all components can be altered by changing the pressure. When the pressure on the system is increased, the volume decreases proportionly. The total number of moles per unit volume will now be more and the equilibrium will shift in that direction in which there is decrease in number of moles i.e, towards the direction in which there is decrease in volume.
Solids whose volume decreases on melting e.g., ice, diamond, carborundum, magnesium nitride and quartz.
Solid (higher volume) \(\text { ⇌ }\) liquid (lower volume)
The process of melting is facilitated at higher pressure, thus the melting point is lowered.
Solids whose volume increase on melting e.g. Fe, Cu, Ag, Au, etc.
Solid (lower volume) \(\text { ⇌ }\) liquid (higher volume)
In this case, the process of melting becomes difficult at high pressure ; thus melting point becomes high. Answer the following two questions based on the above information.
Au(s) \(\text { ⇌ }\)Au(l)
Above equilibrium is favoured at
