The factor concerned by thermodynamics is the inherent tendency or the possibility of the reaction but not eat and rate C(diamond)->C(graphite) is spontaneous, but it is so so that it is not detectable
The factor concerned by thermodynamics is the inherent tendency or the possibility of the reaction but not reality and rate. C (diamond) → C (graphite) is spontaneous, but it is so slow that it is not detectable
