Question

Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction entropy of the following chemical reaction:
S8 + 24F2------ 8S + F6
Round your answer to zero decimal places.J/K

Answer 1

Answer:

$\Delta _rS\°=-2965.27J/K$

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:

$\Delta _rS\°=8*S\°_{SF_6}-S\°_{S_8}-24*S\°_{F_2}$

Thus, considering the ALEKS Data tab, we obtain:

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