Answer : The correct option is, (1)
Explanation :
Entropy : It measures the disorderedness or randomness of the molecule.
That means higher the disorderedness, higher will be the entropy.
As we are going from solid state to liquid state, liquid state to gaseous state, the disorderedness increases due to the less inter-molecular interaction between the molecules.
And, as we are going from gaseous state to liquid state, liquid state to solid state, the disorderedness decreases due to the more inter-molecular interaction between the molecules.
(1)
In this reaction, the disorderedness increases because the state changes from solid to liquid.
(2)
In this reaction, the disorderedness decreases because the state changes from gaseous to solid.
(3)
In this reaction, the disorderedness decreases because the state changes from gaseous to solid.
(4)
In this reaction, the disorderedness decreases because the state changes from gaseous to liquid.
Hence, the correct option is, (1)
