concentration
A study was carried out to find out if the increase in substrate concentration has an appreciable effect on the rate of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was performed 15 times, with an average rate of 7.5 micromoles per 30 minutes and a standard deviation of 1.5. With a substrate concentration of 2.0 moles per liter, 12 reactions were performed, yielding an average rate of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason to believe that this increase in substrate concentration is due to an increase in the rate of reaction?
reason to believe that this increase in substrate concentration causes an increase in the average reaction rate of more than 0.5 micromoles per 30 minutes? Use a significance level of 0.01 and assume that the populations are approximately
