Vedclass · Answer

(B) The entropy change $\Delta S$ is related to the change in the number of moles of gaseous species,$\Delta n_g$. If $\Delta n_g For the reaction $2SO_{2_{(g)}} + O_{2_{(g)}} 	o 2SO_{3_{(g)}}$,the change in gaseous moles is $\Delta n_g = 2 - (2 + 1) = -1$. Since $\Delta n_g$ is negative,the reaction involves a decrease in disorder,leading to a negative value for $\Delta S$.

Which of the following reactions will have the value of $\Delta S$ with a negative sign?
