$SO_2Cl_2(g)$

Vedclass · Answer

(B) Entropy is a measure of the randomness or disorder of a system. For the same substance,the entropy follows the order: $S_{(g)} > S_{(l)} > S_{(s)}$. Comparing the given options,$SO_2Cl_2(g)$ is a gas,which has higher entropy than its solid or liquid forms. While $SO_2(g)$ is also a gas,the question asks for entropy per mole. For $SO_2Cl_2(g)$,the molar mass is $135 \ g/mol$,and for $SO_2(g)$,it is $64 \ g/mol$. Since $SO_2Cl_2(g)$ is a larger,more complex molecule with more atoms and vibrational modes compared to $SO_2(g)$,it possesses a higher standard molar entropy $(S^\circ)$. Therefore,$SO_2Cl_2(g)$ has the highest entropy per mole.
