What does atom economy measure?
The percentage of the total mass of reactants that becomes the desired product.
A reversible reaction reaches an equilibrium position that limits product formation.
A high yield makes more product from each batch of reactants, while a high atom economy means less reactant mass becomes by-products.
The carbon dioxide by-product carries away the other 44% of the reactant mass.
