The rate of a chemical reaction and the equilibrium constant are two different concepts in chemistry. The rate of a reaction refers to the speed at which reactants are converted into products, while the equilibrium constant K is a measure of the relative concentrations of reactants and products at equilibrium.In the reaction between potassium permanganate KMnO4 and oxalic acid H2C2O4 , the rate of the reaction can be influenced by various factors such as concentration, temperature, and the presence of a catalyst. However, changing the rate of the reaction does not directly affect the equilibrium constant.The equilibrium constant is a thermodynamic quantity that depends only on the temperature and the standard Gibbs free energy change of the reaction. It is not affected by the rate of the reaction or the presence of a catalyst. A catalyst can speed up the rate at which equilibrium is reached, but it does not change the equilibrium constant itself.In summary, the rate of the reaction between potassium permanganate and oxalic acid can be manipulated by changing factors such as concentration, temperature, and the presence of a catalyst, but these changes will not influence the equilibrium constant.
