Chemical reaction: The following table shows, for a certain chemical reaction, the rate of reaction R, in moles per cubic meter per second, as a function of the concentration x, in moles per cubic meter, of the product.

a. Use quadratic regression to find a model for the data. Round regression parameters to three decimal places.

b. Use your model to estimate R(24), and explain what your answer means.

c. Estimate the concentration at which the reaction rate is 6 moles per cubic meter per second. (Consider concentrations only up to a level of 50 moles per cubic meter.)
