NaH is an example of :

An example of solid sol is :

Consider the reaction
N₂(g) + 3H₂(g) $$\rightleftharpoons$$ 2NH₃(g)

The equilibrium constant of the above reaction is K_p. If pure ammonia is left to dissociate, the partial pressure of ammonia at equilibrium is given by (Assume that P_NH3 << P_total at equilibrium)

The correct match between item (I) and item (II) is :

Item-I		Item-II
(A)	Norethindrone	(P)	Anti-biotic
(B)	Ofloxacin	(Q)	Anti-fertility
(C)	Equanil	(R)	Hypertension
		(S)	Analgesics
