Chapter 10, Problem 47E

For the reaction
${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\text{(}g{\text{)+4F}}_{\text{2}}\text{(}g\text{)}\to {\text{2CF}}_{\text{4}}\text{(}g{\text{)+H}}_{\text{2}}\text{(}g\text{)}$
$\Delta S\text{°}$ is equal to -358 J/K. Use this value and data fromAppendix 4 to calculate the value of S°for ${\text{CF}}_{\text{4}}\text{(}g\text{)}$ .
