WebOct 27, 2024 · rate = k [ H 2 O 2] describes a reaction that is first order in hydrogen peroxide and first order overall. The rate law: rate = k [ C 4 H 6] 2 describes a reaction that is second order in C 4 H 6 and second order overall. The rate law: rate = k [ H +] [ OH −] WebJan 15, 2024 · rate = k[A][B]2 And is 1 st order in A, 2 nd order in B, and 3 rd order overall. The rate constant can then be evaluated by substituting one of the runs into the rate law (or using all of the data and taking an average). Arbitrarily selecting the first run for this, 0.0347M / s = k(0.01M / s)(0.01M / s)2 This results in a value of k
