Answer:

[tex]\Delta _rS\°=-2965.27J/K[/tex]

Explanation:

Hello,

In this case, for the considered reaction, the standard reaction entropy is computed considering the standard entropy of each product and reactant and their stoichiometric coefficients as shown below:

[tex]\Delta _rS\°=8*S\°_{SF_6}-S\°_{S_8}-24*S\°_{F_2}[/tex]

Thus, considering the ALEKS Data tab, we obtain:

[tex]\Delta _rS\°=8*(291.52J/K)-(430.23J/K)-24*(202.8J/K)\\\\\Delta _rS\°=-2965.27J/K[/tex]

Regards.
