(a) Which of the following reactant concentrations could you use for expeniment 3 in order to determine the rate law, assuming that the rate Law is of the form, Rate =k[A]k [B] [2 Choose all correct poesibilities. [A]=2.7and[B]=1.8[A]=0.9and[B]=5.4[A]=3.6and[B]=1.8[A]=4.5and[B]=1.8[A]=0.9and[B]=3.6[A]=1.8and[B]=3.6[A]=1.5and[B]=1.2[A]=1.8and[B]=5.4 (b) For a reaction of the form, A+B+C,z Products, the following observations aremade: tipling the concentration of A increases the rate by a factor of 3. doubling the concentration of B has no effect on the rate, and doub/ing the concentrationbi Cincreases the rate by a factor of b. Select the correct rate law for this reaction from the choices below. Rate=k[A][D][C]Ratek[A][C]Rate=k[A]2[(C)Pate=k[A][C]2Rate=k[A]2[C]2Rate=k(A]3[C]Plate=k[A][C]3 (c) By what factor will the rate of the reaction described in part (b) above change if the concentrations ol A, B, and C ace all hatved (reduced by a factor of 2 )? The rate will be the ariginal rate multiplied by a factor of
