We can use the following equation to solve for **ΔS˚ _{rxn}**:

$\overline{){\mathbf{\Delta S}}{{\mathbf{\xb0}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{S}}{{\mathbf{\xb0}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{prod}}{\mathbf{-}}{\mathbf{S}}{{\mathbf{\xb0}}}_{\mathbf{f}\mathbf{,}\mathbf{}\mathbf{react}}}$

The given reaction is:

** SnCl**_{4}_{(l)} ⟶ SnCl_{4}_{(g)}

ΔS°_{298} SnCl_{4}_{(l)} = **259 J/mol K**

ΔS°_{298} SnCl_{4}_{(g)} = **366 J/mol K**

Calculate ΔS°_{298} for the following change.

(a) SnCl_{4}(l) ⟶ SnCl_{4}(g)
