Measurements of the concentration, C, of a substance during a chemical reaction at different times t are shown in the table.
| t(h) | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 3.5 | 4.0 | 5.0 | 5.5 | 6.0 |
| C(g/L) | 1.7 | 3.1 | 5.7 | 9.1 | 6.4 | 3.7 | 2.8 | 1.6 | 0.8 | 0.7 | 0.6 |
(a) Suppose that the data can be modeled with an equation in the form:
Determine the coefficients a0, a1, and a, such that the equation best fits the data. Use the equation to estimate the concentration at t =2 h.
Make a plot of the data points and the equation.
(b) Suppose that the data can be modeled with an equation in the form:
Determine the coefficients a0, a1, a2, and a3such that the equation best fits the data. Use the equation to estimate the concentration at t=2 h. Make a plot of the data points and the equation.
