  • The Effect of Substrate Concentration on the Rate of Reaction

    experiment. This is because, if I had the wrong amounts, I would not get a valid conclusion, as I will not know whether my results are affected by the concentration of starch, or whether the results I got were due to the amounts of solution used. This would make both my results and conclusion invalid and unreliable...
