Activation energy is the energy needed to start a chemical reaction. pairing of endergonic and … There is a constant balance of suppy and demand. The chemical reactions of metabolism are reversible, and they, too, would reach equilibrium if they occurred in the isolation of a test tube. Every … What is commonly known as chemical energy, the capacity of a substance to do work or to evolve heat by undergoing a change of composition, may be regarded as potential energy resulting from the mutual forces among its molecules and atoms. Engineering is born from the act of making a mess and being able to put the pieces back together, often with quite innovative results. Balanced reactions, reversibility, and equlibrium.
