Sulfuryl dichloride is formed when sulfur dioxide reacts with chlorine.

the data refer to 298 k.

so2(g) + cl2(g) --> so2cl2(g)

substance: so2(g) + cl2(g) -> so2cl2(g)

delta h� f (kj/mol): �296.8 0�364.0

delta g� f (kj/mol): �300.1 0 �320.0

delta s�(j/kmol): 248.2 223.0 311.9

what is the value of g� for this reaction at 600 k?

The value of of the reaction is 28.38 kJ/mol

Explanation:

For the given chemical reaction:

The equation for the enthalpy change of the above reaction is:

We are given:

Putting values in above equation, we get:

The equation for the entropy change of the above reaction is:

We are given:

Putting values in above equation, we get:

To calculate the standard Gibbs's free energy of the reaction, we use the equation:

where,

= standard enthalpy change of the reaction =-67200 J/mol

= standard entropy change of the reaction =-159.3 J/Kmol

Temperature of the reaction = 600 K

Putting values in above equation, we get:

Hence, the value of of the reaction is 28.38 kJ/mol
