Given information
- The standard free energy of the given reaction is
- The standard free energy of the given reaction is
- The standard free energy of the given reaction is
- The standard free energy of the given reaction is
Step-by-step explanation
Reaction (1):
The given reaction is,
The temperature of the system is , that is .
From Appendix II B,
-
The standard free energy of formation of is .
-
The standard free energy of formation of is .
The standard free energy of the reaction is calculated as,
Therefore, the standard free energy of the given reaction is calculated as,
Substitute the value of the standard free energy of formation of and in the above equation.
Therefore, the standard free energy of the given reaction is .
The value of the standard free energy of the given reaction is different from that calculated in Problem 31 and to calculate the standard free energy of the given reaction at different temperature, the formula with enthalpy change and entropy change should be used.
