The given question is incomplete. The complete question is given here :
The equilibrium constant for the reaction is M.
This value indicates that
A. is a stronger base than
B. HCN is a stronger acid than HONO
C. The conjugate base of HONO is
D. The conjugate acid of CN- is HCN
Answer: A. is a stronger base than
Explanation:
Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.
When ; the reaction is product favoured.
When ; the reaction is reactant favored.
; the reaction is in equilibrium.
As, , the reaction will be product favoured and as it is a acid base reaction where
acts as acid by donating
ions and
acts as base by accepting
Thus is a strong acid thus
will be a weak conjugate base and
is a strong base which has weak
conjugate acid.
Thus the high value of K indicates that is a stronger base than
