Answer : The [tex]\Delta S[/tex] system for this change is, negative [tex](-\Delta S)[/tex].
Explanation :
Entropy : It measure the randomness and the disorderedness of the system.
As we know that the entropy increases, [tex](+\Delta S)[/tex] as we are moving from the solid state to liquid state and liquid state to gaseous state and the entropy decreases, [tex](-\Delta S)[/tex] as we are moving from gaseous state to liquid state and liquid state to solid state.
The given reaction is,
[tex]O_2(g)\rightarrow O_2(aq)[/tex]
In this reaction, the phase changes from gaseous state to liquid or aqueous state. That means the entropy of the system for this change will be negative.
Hence, the [tex]\Delta S[/tex] system for this change is, negative [tex](-\Delta S)[/tex].
