2.
As products are formed in the reaction
NH4Cl(s) + 3.5 kcal
H2O
NH4+(aq) + Cl (aq),
the entropy of the system
(1) decreases and heat is absorbed
(2) decreases and heat is released
(3) increases and heat is absorbed
(4) increases and heat is released

Answer :

The entropy of the system increases and heat is absorbed in this chemical reaction.

What happen when NH4Cl reacts with water?

When ammonium chloride NH4Cl reacts with water, it absorb energy for the surrounding and decomposes into its component ions such as NH4+ and Cl- so we can conclude that increases occur in the entropy of the system and heat is absorbed.
