Donc tu as ta formule ∆G = ∆H –T. ∆S 

ici ∆H= -60KJ.mol-1 =-60000 J.mol-1

    T= (273+25)=298K

    ∆S= -200 J.mol-1.K-1 

Du coup tu remplaces: ∆G = -60000-298 x (-200)

                                       ∆G= -400 J.mol-1 < 0 donc exergonique 

 

en fait tu dois juste faire attention aux unités soit tu mets tout en J soit tout en KJ 

c'est bon pour toi? 🙂
