Once ten minutes elapsed, the H2C2O4 solution was quickly added to the KMnO4 solution. The solution was thoroughly mixed with a glass stirring rod and placed in a spectrometer to visualize the absorbency decrease. The reaction order with respect to the reactants was determined using the method of initial rates. molar concentrations (mol/L) and the superscripts x and y represent the reaction order of each adjacent concentration1. You should have found that the reaction was first order in permanganate and first order in oxalate thus giving a rate equation: Rate = k[KMnO 4][H 2 C 2 O 4] You should have seen that the the potassium permanganate discolours in the oxalic acid solution much more slowly than in the iron(II) sulfate solution. Once the last hint of red had vanished, the timer was stopped and data was recorded in data table one. 1. the method of initial rates involves substituting the initial reactant concentrations into rate calculations.

So, the reaction you performed was likely just the same mechanism that you have seen everywhere else. Changes in concentrations of individual reactants and the effect on the rate can be expressed mathematically through the rate equation (1): rate= k[H2C2O4]x [KMnO4]y (1). Oxalic acid concentration raised to some power y. Determination 2 was performed using the above procedure and a water bath temperature of 38 °C. The average factor by which reaction rate increased with each 10 °C increase resulted in 2. Equation (2): (rate2)/(rate1)= ([H2C2O4]1x [KMnO4]1y)/([H2C2O4]2x [KMnO4]2y) (2) was used to solve for the reaction order (X). In this equation, k is the rate constant which only varies with changes in temperature. This is quite a complex oxidation reduction reaction. Each initial concentration resulted in a unique reaction rate; these rates were then examined using the method of initial rates to determine the order of the reaction with respect to both KMnO4 and H2C2O4. total surface area that is in contact with oxygen in the air) reacts explosively
