Refer to Data Table B, in which you entered rate constants. In the spaces below, enter your rate constants, highest to lowest . Do not include units. Rate Constants, in M -1 s -1 1.1e-5 6.3e-6 5.9e-6 3.2e-6 3.2e-6 a. What is the range of these values (highest - lowest)? 7.8e-6 b. What is the average of these values? 5.9e-6 The remainer of this question is designed to help you decide if the data from one of your experiments can be discarded. To quantitatively "throw out" a measurement, you must perform a statistical test on your data called a Q-Test . The formula for the Q-test is Q calculated = gap/range where gap = (questionable value - next closest number) and range = (largest number - smallest number). Q calculated is then compared to Q table . If Q calculated > Q table then the questionable datum can be discarded. Q (90% confidnece) Number of measurements 0.76 4 0.64 5 0.56 6 c. What is the gap of these values (questionable value - next closest value)? (Take the absolute value if necessary to make this number positive.) 4.7e-6
