Question
An example of a reversible reaction is :
Options
A.Pb(NO3)2(aq)+ 2Nal(aq) ⇋ PbI2 (s) + 2NaNO3(aq)
B.AgNO3(aq)+ HCl(aq) ⇋ AgCl(s)+HNO3(aq)
C.2Na(s) + H2O(l) ⇋ 2NaOH(aq)+ H2(g)
D.KNO3(aq) + NaCl(aq) ⇋ KCl(aq) + NaNO3(aq)
Solution
In (a) and (b) Pbl2 and AgCl separates out as precipitate hence they are irreversible reactions.
In (c), H2 escapes out as gas (d) is reversible reaction as noe of the reactants / prosucts separate out.
