    permanganate (KMnO4) and oxalic acid (H2C2O4)‚ three determinations were performed‚ each with different initial concentrations of the reactants. 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. The rate constant (k)‚ was then calculated‚ and the rate equation for the reaction written1. In part two; determinations were done at varying temperatures while keeping
