Question

The following set of data was obtained by the method of initial rates for the reaction: S2O8^2-(aq) + 3I-(aq) ? 2SO4^2-(aq) + I3^-(aq) Initial Rate Data Experiment | Initial [S2O8^2-], (M) | Initial [I-], (M) | Initial Rate, (M s^-1) ---|---|---|--- 1 | 0.25 | 0.10 | 9.00 x 10^-3 2 | 0.10 | 0.10 | 3.60 x 10^-3 3 | 0.20 | 0.30 | 2.16 x 10^-2 What is the rate law for the reaction? Rate = k[S2O8^2-][I-] Rate = k[S2O8^2-]^2[I-]^2 Rate = k[S2O8^2-][I-]^2 Rate = k[S2O8^2-]2[I-] Rate = k[S2O8^2-]2[I-]^3

Step 1

The general form of a rate law is: Rate = k[A]^m[B]^n where: - k is the rate constant, - [A] and [B] are the concentrations of the reactants, - m and n are the orders of the reaction with respect to [A] and [B] respectively. The problem does not provide the Show more…
