Chemical Reaction A chemical reaction begins when a certain mixture of chemicals reaches 95^°C. The reaction activity is measured in units (U) per 100 microliters of the mixture. Measurements during the first 18 minutes after the mixture reaches 95^°C are listed in Table 2.15.

a. Find a logistic model for the data. What is the limiting value for this logistic function?

b. Use the model to estimate the average rate of change of the reaction activity between 7 minutes and 11 minutes.

c. Numerically estimate to the nearest thousandth by how much the reaction activity is increasing at 9 minutes.

d. Write sentences of interpretation for the answers to parts b and c.
