Explanation
The equilibrium constant does not change with change in volume (pressure or concentration). Hence the equilibrium constant remains same.
Catalysts will increase the rate of reaction. But it doesnot affect the equilibrium constant (KC).
Argon is an inert gas. When an inert gas is added to the system in equilibrium at constant volume , the total pressure will increase . But the concentration of the produce and reactants (i.e ratio of their moles to the volume of the container) will not change . Hence, when an inert gas is added to the system in equilibrium at constant volume there will be no effect on the equilibrium.
From the Bronsted-Lowry theory of acids and bases,
→ An acid is a proton (Hydrogen ion , H+) donor
→ A base is a proton (H+ ion) acceptor.
O2- (base) + H2O (acid) →OH− (C·B) + OH−(C·A)
Hence O2- acts as a Lewis base by donating a pair of electrons.
Amines contain lone pair of electron on nitrogen atom. Hence amines behaves as Lewis base.
