Question

Tabulated below are initial rate data for the reaction 2Fe(CN)₆^3- + 2I^- → 2Fe(CN)₆^4- + I₂ What is the value of k?

Quizplus · Accepted Answer

The rate law for the reaction can be written as rate = k[Fe(CN)₆^3-][I^-]. Using the given initial rate data and substituting the corresponding concentrations, we can calculate the value of k. For example, taking the first set of initial rate data: 0.10 M/s = k[(0.010 M)(0.010 M)] k = 100 M^-2 s^-1 Doing the same calculation for all the other initial rate data and taking the average, we get k = 10 M^-2 s^-1. Therefore, the correct answer is choice C.
