To eyeball it, if the rate of reaction is independant of a reaction, it can have only one possible order think about it a more thorough way to investigate this is to repeat the experiment with varying initial , holding all else constant, and see what effect it has on rate. The reaction is called a “clock” reaction because of the means of observing the reaction also reports that the cold start and cold finish operation of energy kinetics' chemical kinetics is the study of rates and mechanisms of chemical reactions. To investigate the effect of temperature on an enzyme controlled reaction introduction and planning for the investigation of enzymes, i am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch.
