Determined experimentally
WebFeb 2, 2024 · The experimentally determined rate law is therefore rate = k [A] 2 [B] 0 = k [A] 2 We can now calculate the rate constant by inserting the data from any row of Table 14.3.1 into the experimentally determined rate law and solving for k. Using Experiment 2, we obtain 19 × 10 −3 M/min = k (0.75 M) 2 3.4 × 10 −2 M −1 ·min −1 = k WebMar 5, 2024 · Therefore, f must be determined experimentally. The Moody diagram relates f to the pipe wall relative roughness ( /D) and the Reynolds number (Figure 4.2). Instead of using the Moody diagram, f can be determined by utilizing empirical formulas.

WebUsually, the steps are either given or determined experimentally. One way to go about writing the steps is if you are given the original equation and any intermediates, as you know that they intermediates must be produced and then used. So, to answer your question, it is trial and error in experiments, as far as I am aware. Hope this helps. Comment
WebA rate law shows how the rate of a chemical reaction depends on reactant concentration.
