Can a reaction be classed as 'feasible' or 'spontaneous' if its activation energy has not been met?

No, I don't think so.

No, I don't think so.
But the equation for Gibb's free energy does not consider kinetic stability of a system. This means that the value for Gibb's free energy can fall below zero, thus be thermodynamically 'feasible' even if the activation energy for the reaction is not met. In this case, the reaction wouldn't proceed / be infinitesimally slow (as activation energy has not been met by all reactant particles), even though the system's thermodynamics are all good to go (i.e. the reaction is technically 'feasible'), no?

That actually makes sense! But I don't think 'feasible' is the right word as the activation energy is not easily being met (Is it, i'm confusing myself lol)?

Honestly, the word 'feasible' has confused me so much but I kinda get it now. I just had to forget what 'feasible' usually means in the English language.

Hahaha that's what got me too, the logic was correct but that word was just messing the whole thing up! xD
