Vedclass · Accepted Answer

$NaNO_{3_{(s)}} \longrightarrow Na^{+}_{(aq)} + NO_{3^{-(aq)}}$

Vedclass · Answer

(C) Entropy $(S)$ is a measure of the randomness or disorder of a system. In the reaction $NaNO_{3_{(s)}} \longrightarrow Na^{+}_{(aq)} + NO_{3^{-(aq)}}$,a solid substance dissolves to form aqueous ions. The aqueous phase possesses higher disorder and randomness compared to the solid phase. Therefore,the entropy of the system increases in this process. In other options,either the number of gas moles decreases or the system transitions from a more disordered state to a more ordered state (like precipitation),leading to a decrease in entropy.

Which of the following equations indicates an increase in entropy?
