what are $2-3$ feasible reactions to carry out in a school lab to determine their activation energy with and without a catalyst? please indicate which catalyst can be used for each and ensure there are literature values to compare with. also please write the procedure on how to conduct the experiment with detailed method and specific measurements$/$materials$/$quantity of chemicals to be used. i dont want anything with like spectrometry i want something with like a chemical you swirl it then see how long it takes to change color
