Salut @clairecamp21

Sur la grille officielle, l'item est bien vrai !

Beh justement, le sodium et le potassium sont tous les deux positifs (Na+ et K+)

Du coup :

ddp = - RT/zf x \Deltalnf

Donc on a z positif.

Donc si T augmente, ddp diminue en valeur relative. Donc augmente en valeur absolue car elle est négative.
