Expert Solution
Step 1

In this question, standard Gibb's free energy change at 700 K for the given reaction is to be determined.

 

Step 2 Standard Gibb's free energy change

Standard Gibb's free energy change :

It is the amount of free energy when a reactant is converted into product at standard conditions.

It can be calculated by using the following formula given below :

∆G° = ∆H° - T ∆S°                                     .................. (1)

Where,

∆G° = standard Gibb's free energy change

∆H° = standard enthalpy change

T = temperature

∆S° = standard entropy change
