उत्तर

Thermodynamics feasibility of a reaction depends on Gibbs free energy i.e., AG must be negative for spontaneous process. Kinetic feasibility depends on the activation energy of reaction, the lesser is the activation energy, the greater is the feasibility of reaction, i.e.,

i.e., Diamond `->` Graphic ΔG = – ve

This process is thermodynamically feasible but it is very slow due to its high activation energy.
