Coucou, je vais essayer de te faire la correction 

Alors : 

A- Faux, elle est exothermique dans le sens 1 car ΔH < 0 

B- Vraie car ΔG < 0 

C- Faux car quand ΔG < 0, alors K>1

D- Faux car car tu augmentes la température dans ses conditions, la réaction va dans le sens 2 

E- Faux car ΔG° = ΔG - RTln(k) donc a l’équilibre ΔG = 0 donc ΔG° = -RTln(k)

Bien sur, attend la certification des tuteurs mais il me semble que c’est ca !! 

J’espère que tu as bien compris sinon hésites pas a me demander, je pourrais peut etre t’aider :)))
