Make a non-spontaneous process spontaneousA process that is nonspontaneous can be made spontaneous by coupling it with another process tha is highly spontaneous.The coupling of nonspontaneous reactions with highly spontaneous ones is important in biological system. The oxidization of glucose, for example, is highlyspontaneous:C6H12O6(s) + 60₂(g) → 6 CO₂(g) + 6 H₂O(1)Spontaneous reactions such as this ultimately drive the nonspontaneous reactions necessary to sustain life. Can you use Gibbs free energy, enthalpy, and entropyto argue this reaction is highly spontaneous? Gibbs free energy (G) is a measure of thespontaneity of a chemical reaction. It is thechemical potential for a reaction, and is minimizedat equilibrium.
