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 condition of determination 1,2,and3
a) What assumption did you make about the reaction of KMno4 solution and H2C2O4 solution in those determination that allowed you to consider k to be a constant
