explain this given problem :
Dear student
we will discussed the position of equilibrium as
Addition of an inert gas at constant pressure:
When an inert gas is added to the system in equilibrium at constant pressure, then the total volume will increase. Hence, the number of moles per unit volume of various reactants and products will decrease. Hence, the equilibrium will shift towards the direction in which there is increase in number of moles of gases.
Addition of an inert gas at constant volume:
When an inert gas is added to the system in equilibrium at constant volume, the total pressure will increase. But the concentrations of the products and reactants (i.e. ratio of their moles to the volume of the container) will not change.
so, when an inert gas is added to the system in equilibrium at constant volume there will be no effect on the equilibrium.
We also knew that if change in number of gaseous molecules, , then equilibrium is unaffected.
Hence option (B) is correct.
