The rate for a bimolecular gas-phase reaction, A + B → product, predicted by collision theory is = = ()where: k is the rate constant in units of (number of molecules) −1 ⋅s −1 ⋅m 3.; n A is the number density of A in the gas in units of m −3.; n B is the number density of B in the gas in units of m −3.E.g. for a gas mixture with gas A concentration …
WebJul 4, 2024 · Enzymes are catalysts that drive reaction rates forward. Most catalysts, but not all, are made up of amino acid chains called proteins that accelerate the rate of reactions in chemical systems. The functionality of a catalyst depends on how the proteins are folded, what they bind to, and what they react with. WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
