- The equation used to calculate entropy change is of a reaction is:
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
