Detailed Solution

  • Thermodynamic feasibility of a reaction depends on Gibbs free energy i.e. G must be negative for a spontaneous process, while its value should be positive for a non-spontaneous process.
  • Kinetic feasibility depends on the Activation energy of the reaction.
  • Lesser the Activation energy, greater is the feasibility of the reaction.
  • For example, for the reaction, DiamondGraphite, G=-ve.
  • This process is thermodynamically feasible, but it is very slow due to its high activation energy.
