Mical reaction
WebbGibbs free energy and spontaneity. When a process occurs at constant temperature \text T T and pressure \text P P, we can rearrange the second law of thermodynamics and define a new quantity known as Gibbs free energy: \text {Gibbs free energy}=\text G =\text H - \text {TS} Gibbs free energy = G = H − TS. Webb2 sep. 2024 · Michael reaction is three step reaction. It is carried out with conjugated substrates. These reactions are carried out in protic solvents with a catalytic amount of base. Step 1 (Deprotonation) The first step of the Michael reaction is deprotonation. In this step, the base attack the acidic hydrogens.
