An example of a reversible reaction is

A

`Pb(NO_(3))_(2)(aq)+2NaI(aq) rarr PbI_(2)(s)+2NaNO_(3)(aq)`

B

`AgNO(3)(aq)+HCl(aq) rarr AgCl(s)+HNO_(3)(aq)`

C

`2Na(s)+H_(2)O(l) rarr 2NaOH(aq)+H_(2)(g)`

D

`KNO_(3)(aq)+NaCl(aq) rarr Kcl(aq)+NaNO_(3)(aq)`

Text Solution

Verified by Experts

The correct Answer is:
D
The reactions (a) and (b) precipitation reactions, they are not reversible. Reaction (d) is an -exchange reaction. Hence, it is a reversible reaction.
`KNO_(3)(aq)+NaCl(aq) rarr KCl(aq)+NaNO_(3)(aq)`
