Vedclass · Answer

(B) Step $1$: Entropy $(S)$ is a measure of the randomness or disorder of a system. $A$ negative $\Delta S$ implies a decrease in randomness.Step $2$: Dissolving sugar in water increases disorder as the solid lattice breaks down into solution $(\Delta S > 0)$.Step $3$: Adsorption of a gas on a solid surface restricts the movement of gas molecules, leading to a decrease in disorder $(\Delta S Step $4$: The reaction $2NH_3(g) \rightarrow N_2(g) + 3H_2(g)$ increases the number of moles of gas from $2$ to $4$, increasing disorder $(\Delta S > 0)$.Step $5$: Sublimation of dry ice $(CO_2(s) \rightarrow CO_2(g))$ involves a transition from solid to gas, which significantly increases disorder $(\Delta S > 0)$.Conclusion: Option $B$ is the correct answer.

Which of the following processes has a negative $\Delta S$ (change in entropy)?
