From past experiments I think that the higher the concentration, the faster the reaction will be. There are many different factors that could also speed up a reaction such as: surface area Temperature Catalysts And concentration. I have chosen to change the concentration because you can control it better than the others, and it is very clear to see what has been affected. I also think that I will get the most noticeable differences between each experiment. Temperature would be very hard to control, and it wouldn't stay constant - it would get hotter or colder all the time. Surface area would be good...
