Explain the difference between the spontaneity of a reaction (which depends on thermodynamics) and the speed at which the reaction occurs (which depends on kinetics). can a catalyst make a nonspontaneous reaction spontaneous?

Flourine has electron affinity less than that of chlourine why? Confussion is if electrons in flourine are tightly packed means it has high density then when electron is added in it its remainig electron should repel it so more energy will b release
