Environmental scientists and engineers dealing with the impacts of acid rain must determine the value of the ion product of water Kw as a function of temperature. Scientists have suggested the following equation to model this relationship:
where Ta = absolute temperature (K), and a, b, c, and d are parameters. Employ the following data and regression to estimate the parameters:
T(K) | Kw |
0 | 1.164 × 10−15 |
10 | 2.950 × 10−15 |
20 | 6.846 × 10−15 |
30 | 1.467 × 10−14 |
40 | 2.929 × 10−14 |
