The initial concentration of reactants plays a significant role in determining the rate of reaction and the final yield of the product in a chemical reaction. In the reaction between potassium permanganate KMnO and oxalic acid HCO , the rate of reaction and the final yield of the product can be affected by the initial concentration of both reactants.1. Rate of Reaction:The rate of a reaction is directly proportional to the concentration of the reactants. According to the collision theory, an increase in the concentration of reactants leads to more frequent collisions between the particles, resulting in a higher reaction rate. In the case of the reaction between KMnO and HCO, if the initial concentration of either or both reactants is increased, the rate of reaction will also increase.The reaction between KMnO and HCO can be represented by the following balanced equation:2 KMnO aq + 5 HCO aq + 3 HSO aq KSO aq + 2 MnSO aq + 10 CO g + 8 HO l 2. Final Yield of Product:The final yield of the product depends on the stoichiometry of the reaction and the limiting reactant. The limiting reactant is the reactant that is completely consumed during the reaction and determines the maximum amount of product that can be formed.In the reaction between KMnO and HCO, if the initial concentrations of both reactants are in the stoichiometric ratio 2:5 , then both reactants will be completely consumed, and the final yield of the product will be maximum. However, if the initial concentrations of the reactants are not in the stoichiometric ratio, one of the reactants will be in excess, and the other will be the limiting reactant. In this case, the final yield of the product will be determined by the limiting reactant.For example, if the initial concentration of KMnO is higher than the stoichiometric ratio, KMnO will be in excess, and HCO will be the limiting reactant. The final yield of the product will be determined by the amount of HCO present, and any excess KMnO will remain unreacted.In summary, the initial concentration of reactants affects the rate of reaction and the final yield of the product in the reaction between potassium permanganate and oxalic acid. An increase in the initial concentration of reactants will result in a higher reaction rate, while the final yield of the product will depend on the stoichiometry of the reaction and the limiting reactant.
