The
for the reaction is 54.425 kJ/mol
Explanation:
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,
R = Gas constant =![8.314J/K mol](/tpl/images/0039/7802/a0934.png)
T = Temperature =![25^oC=[25+273]K=298K](/tpl/images/0039/7802/df1f6.png)
Putting values in above equation, we get:
Hence, the
for the reaction is 54.425 kJ/mol
