For the reaction, 
, 
at 300 K .
Hence, 
is
Text Solution
Verified by ExpertsThe correct answer is:
B
The change in Gibbs free energy is given by
where,
change enthalpy of the reaction
change entropy of the reaction
Thus, in order to determine 
, the values of 
must be known. The value of 
can be calculated by using equation
….(i)
where, 
change in internal energy using
number of moles of gaseous products
-number of moles of gaseous reactants
gas constant 
Given, 
By putting the values in Eq. (i) we get,
Hence,
