Polyurethane stoichiometry calculation

WebAn active intermediate is a molecule that is in a highly energetic and reactive state It is short lived as it disappears virtually as fast as it is formed. They are short lived C A 10-14 s and present in very low concentrations. That is, the net rate of reaction of an active intermediate, A*, is zero. The assumption that the net rate of reaction is zero is called the Pseudo … WebA. ATP binding stoichiometry.
