How to speed up chemical reactions
WebFeb 12, 2024 · A reaction is "completed" when it has reached equilibrium — that is, when concentrations of the reactants and products are no longer changing. If the equilibrium constant is quite large, then the answer reduces to a simpler form: the reaction is completed when the concentration of a reactant falls to zero. WebOct 18, 2024 · Cells can die if these reactions occur too slowly, so they produce enzymes to increase the speed of these reactions at body temperature. They do this by binding their substrates, catalysing their chemical reactions and, finally, releasing the products. “Enzymes are the catalysts of life,” Judith explains.
