<u>Answer:</u> The for the reaction is 54.425 kJ/mol
<u>Explanation:</u>
For the given balanced chemical equation:
We are given:
To calculate for the reaction, we use the equation:
For the given equation:
Putting values in above equation, we get:
Conversion factor used = 1 kJ = 1000 J
The expression of for the given reaction:
We are given:
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 = 46900 J
R = Gas constant =
T = Temperature =
= equilibrium constant in terms of partial pressure = 20.85
Putting values in above equation, we get:
Hence, the for the reaction is 54.425 kJ/mol
