hi, I need MAJOR help with this question, i can't find any info thats very useful on the net and my HSC syllabus is just confusing me further. If anyone has any idea please please please help!

Question: Design a method to investigate how the concentration of potassuim iodide (KI) affects the rate of reaction. Your method should be detailed enough so anyone could repeat what you have done.

Thanks in advance :wave:

It just requires you design an experiment, you need to understand you independant variable (which in this case should be the catalyst (the potassium iodide)) and the dependant variable which in this case is the reaction. Measure the rate of reaction withought the catalyst and compare this to the rate of reaction withught it. If you talk through this in order of how you DID it then people will be able to repeat it
