Consider the results from Experiments 1, 2 and 3 in Question 9. Compare the rate (1/ Dt) for Experiment 1 with the rates in Experiments 2 and 3 where the concentration of [I-] and [S2O82-] are halved. Is the following statement true or false?Rate is proportional to [I-aq]2

Which of these reactions are you going to measure the rate of in this experiment?Question 1Answer2I–(aq) + H2O2(aq) + 2H+(aq) → I2(aq) + 2H2O(l)I2(aq) + 2S2O32–(aq) → 2I–(aq) + S4O62–(aq)

How is the effect of concentration changes on the reaction rate seen in the rate law?A.The rate law does not show how concentration changes would affect the reaction rate.B.A change in concentration of a reactant would change the exponent of that reactant.C.The effect of concentration changes on the rate constant affects the reaction rate.D.The exponents determine how much concentration changes affect the reaction rate.SUBMITarrow_backPREVIOUS

Consider two reactions, one that is second order and one that is third order. Which best describes the effect on the reaction rates by DECREASING the concentration of all reactants?Select answer from the options below

Which of the following statements is true?Select answer from the options belowThe rates of SN1 and SN2 reactions are not dependent on the concentration of the nucleophile.Only the rate of an SN1 reaction (not the rate of SN2 reaction) is dependent on the concentration of the nucleophile.Only the rate of an SN2 reaction (not the rate of SN1 reaction) is dependent on the concentration of the nucleophile.The rates of SN1 and SN2 reactions are highly dependent on the concentration of the nucleophile.

Which of the following shows how rate depends on concentrations of reactants?A.PV = nRTB.C.D.Rate = k[A]m[B]nSUBMITarrow_backPREVIOUS
