1) Entropy change in condensation of water is NEGATIVE

2) Entropy change in mixing acidi and water is POSITIVE

3) Entropy change is NEGATIVE in formation of 2H₂O(l) from 2H₂(g) and O₂(g)

4) Entropy change is POSITIVE in production of NO₂ from N₂O₄

_{5) Entropy change is NEGATIVE in Crystallization process}

Step-by-step explanation

Entropy is the thermodynamic property denoted by "S".

Degree of randomness or disorderness in a system is known as Entropy

1) condensation is a process of conversion of water vapour into liquid.

Water vapour has maximum randomness it can move all possible direction, but when it convert into liquid it's randomness is decreas as water molecules is bonded by hydrogen bond in liquid phase.

2) When acid mixed in water then acid ionised and hence acid dissociate so number of atom is increase in water and increasing number of atom increased the randomness.

So entropy change will be positive

3) H₂ and O₂ is a gaseous molecules and the gaseous molecules has maximum randomness among all phase when these H₂ and O₂ gas combine and form H₂O(l) thn the randomness of a system is decreased hence change in Entropy is Negative.

4) production of NO₂ from N₂O₄ is required the heat energy to break N₂O₄ so after acquiring the heat the kinetic energy of the obtained molecule is increases so randomness is increases , hence the Change in Entropy is Positive.

5) When molecules or atoms Crystallizes then they get attained an ordered arrangement and hence randomness is decreas so change in Entropy is Negative
