WebThe K values give us an idea of the relative amounts of products and reactants at equilibrium. If K is large, there is a large amount of H⁺ or OH⁻ at equilibrium and very little undissociated acid or base. We have a strong acid or base. If K is very small, there is very little H+ or OH- at equilibrium, and mostly undissociated acid or base. WebTools. In chemical kinetics a reaction rate constant or reaction rate coefficient, k, quantifies the rate and direction of a chemical reaction. [1] For a reaction between reactants A and B to form a product C: a A + b B → c C. where. A and B are reactants. C is a product. a, b, and c are stoichiometric coefficients.
