How do chemists determine reaction mechanisms
WebThe rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity. WebHow do chemists determine reaction mechanisms? Probably using theory, the identity of the products and reactants, observations made. I can’t even begin to think how much more involved it is.
