Determine the rate law and the value of k for the following reaction using the data provided: S2O8^2- (aq) +3I- (aq) = 2SO4^2-(g) + I3- (aq) [S2O8^2-]i (M) [I-]i (M) Initial Rate (M^-1 s^-1) 0.30 0.42 4.54 0.44 0.42 6.65 0.44 0.21 3.33 Answer Choices: A) Rate = 120 M^-2 s^-1 [S2O8^2-][I^-] B) Rate = 36 M^-1 s^-1 [S2O8^2-][I^-] C) Rate = 86 M^-2 s^-1 [S2O8^2-][I^-]^2 D) Rate = 195 M^-3 s^-1 [S2O8^2-][I^-]^2 E) Rate = 23 M^-1/2 s^-1 [S2O8^2-][I^-]^1/2 Please help me. I'm so lost and have no idea how to solve this problem.
