When you calculated k in the rate equation for the reaction of KMnO4 solution and H2C2O4 solution you assumed k had the same value under the conditions of determinations 1,2, and 3.
A) What assumption did you make about the reaction of KMnO4 solution and H2C2O4 solution in those determinations that allowed you to consider k to be a constant?
B) Would it be sound practice to compare the results of determinations 4 through 6 when calculating k? Briefly explain.
