Pure ammonia is placed in a vessel at temperature where its dissociation (α) is appreciable. At equilibrium

A.Kp does not change significantly with pressure✓ Correct

B.does not change with pressure

C.Concentration of NH3 does not change with

D.Concentration of H2 is less than that of N2

Explanation

Because if we increase the pressure then according to Le Chatelier’s principle, equilibrium will shift in such a direction so as to undo effect of change. So P K will remain unchanged
