👉 The term "predissolve" in the context of chemical reactions refers to a state where the rate constant for the reaction is zero, indicating that the reaction has reached equilibrium. In other words, the concentration of reactants and products are equal at all times, except for the time interval during which the reaction is taking place. This condition occurs when the product concentration equals the reactant concentration in such a way that there is no net change in the amount of product or reactant present.
