WebSep 2, 2024 · Determine your reaction’s products and reactants. Any chemical reaction involves two categories of chemicals — products and reactants. Products are the chemicals created by the reaction, while reactants are the chemicals that interact, combine, or break down to make the product. In other words, the reactants of a reaction are like the …
WebThe reaction quotient, Q, is a measure of the relative amounts of reactants and products during a chemical reaction at a given point in time. By comparing the value of Q to the equilibrium constant, K eq, for the reaction, we can determine whether the forward reaction or reverse reaction will be favored.
