From the observed rate that the ice vanished and computer simulations, the scientists concluded that the ice was 99percentt pure water instead of a half-and-half mix of ice and dirt as they had expected.
Observed rate constant of the association reaction.
The predicted and observed rate constants were in good agreement.

Specific rate constant was found to be more suitable for the description of adsorption kinetics than observed rate constant.
The observed rate constant was similar to that observed by us previously and others on similar systems [7, 8].
However, when empirically calibrated and related to tide range, the transport equation adequately accounts for observed rates.
The maximum difference between the lowest (CT/Ca2+ = 0.13; r = 0.00016) and highest (CT/Ca2+=10; r = 0.9997) observed rate was 3-fold.
So, the observed rate constant kobs can be expressed by the Smoluchowski expression[1]: k obs = 4 πDR, (1).
Postulated and observed rates of reaction, based on oxidation by H2O molecules, are in a very high correlation.
The observed rate constant associated with a water flow rate of 0.37 L m−1 and a single Type B catalyst charge containing 57.6 g Fe.
