Given information
The Gibb’s free energy, , of the reaction is calculated as,
The reaction is spontaneous for the negative value of Gibb’s free energy.
Step-by-step explanation
Step 1.
The enthalpy change of the reaction is , that is .
The absolute temperature of the reaction is
The entropy change of the reaction is
The Gibb’s free energy, , of the reaction is calculated as,
Substitute the value of enthalpy change, absolute temperature and entropy change of the system in the above equation.
Therefore, the Gibb’s free energy of the reaction is
Since the value of Gibb’s free energy is not negative, the reaction is non-spontaneous.
