Organic Chemistry 1 PLTLWorksheet 5Name:________________________1.The following is a common synthesis used in the organic chemistry laboratory course.When the concentration of methoxide ion is doubled (CH3O-), the reaction rate doubles.When the concentration of 1-bromobutane is tripled, the reaction rate triples.a.What is the order of this reaction with respect to 1-bromobutane? Write the rateequation for this reaction. What is the overall order?b.What will you see when you run the reaction (using the same amount of reagent) inhalf the volume of solvent?2.Consider the following reaction-energy diagram.a.Label the reactants and products. Label the activation energy for the first step andthe second step.b.Is the overall reaction endothermic or exothermic? What is the sign of∆H°?c.Which points in the curve correspond to intermediates? Which to transition states?d.Label the transition of the rate-limiting step. Does its structure resemble, the products, or anintermediate?3.
