Meredith Robbins Inquiry Lab (PH) 10/27/14 Research Question: What conditions would affect the rate of an enzymatic reaction? Null Hypothesis: The Ph and the temperature will not have an effect on the rate of enzymatic reactions. #1 Alternative Hypothesis: The Ph and temperature will have an effect on the rate of enzymatic reactions. #2 Alternative Hypothesis: The Ph and temperature will not have an effect on the rate of enzymatic reactions. Control group: The Ph level of 7 (neutral) Experimental group: Ph- 3, 5, 7, 9, 11 (I will get data for Ph 5 and 7) IV: the Ph level DV: the rate of the enzyme reactions
