Chemical kinetics order of reaction and activation energy

ultranova3 SG

Hi
I did my experiment on kinetic today. reaction between iodide and persulfate. However, i feel that my results are screwed.
Have anyone done this experiment before? can you tell me the order of reaction wrt to iodide and persulfate, and rate constant for the whole equation.

I have a feeling it will be order one wrt to iodide and one wrt to persulfate but my experiments data give different results.

And also for reaction between permanganate and oxalic acid, what is the activation energy required?

Thank you in advance. Rolling Eyes

i also believe is of first order for both reactants.

is your expt. skill b or c? one of them doesn’t care about your results.

This one is not SPA.
I have found out one exercise: yeah my feeling is correct, first order wrt to iodide and first order wrt to persulfate.
now i need to find value k.
Have anyone did this exercise, can help me find value of k?
