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  

So, the value of Gibb’s free energy is negative, the reaction is spontaneous.
