<u>Answer:</u> The for the reaction is 74.732 kJ/mol
<u>Explanation:</u>
For the given chemical reaction:
The expression of for the given reaction:
We are given:
Partial pressure of solids are taken as 1.
Putting values in above equation, we get:
To calculate the Gibbs free energy of the reaction, we use the equation:
where,
= Gibbs free energy of the reaction = ?
= Standard Gibbs' free energy change of the reaction = 102 kJ = 102000 J (Conversion factor: 1 kJ = 1000 J)
R = Gas constant =
T = Temperature = 298 K
= equilibrium constant in terms of partial pressure =
Putting values in above equation, we get:
Hence, the for the reaction is 74.732 kJ/mol
