- A student reacts 2-pentene with H2(g) and chooses iron (Fe) as his catalyst. Identify the outcome the student will get from this reaction.arrow_forwardThe conversion of (CH3)3CI to (CH3)2C=CH2 can occur by either a onestepor a two-step mechanism, as shown in Equations [1] and [2]. Question: Assume Equation [2] represents an endothermic reaction and that the product of the rate-determining step is higher in energy than thereactants or products. Draw an energy diagram for this two-stepreaction. Label the axes, reactants and products for each step, and theEa and ΔHo for each step. Label ΔHo overall. Draw the structure for bothtransition states.arrow_forwardA catalyst is a. A substance which increases the rate of a reaction by adding heat to it. b. A substance which increases the rate of a reaction without being used up in the reaction. c. An intermediate in a reaction which influences its rate. d. A solid which provides a "kick start" for the reaction, but is not affected by it.arrow_forward
- Given the Rate Law Equation Rate = k [cpd A]3[cpd B]2, what happens to the Rate, if the molarity of compound A is tripled and the molarity of compound B is reduced to 1⁄4 of its original value?The Rate of the reaction will increase by a factor of ___________arrow_forwardChoices in second item: 1. How many steps are there in the reaction? ( 0, 1, 2, 3, 4) 2. How many transition states are there? (0, 1, 2, 3, 4) 3. How many intermediates are there? (0, 1, 2, 3, 4) 4. What is the letter symbol of the transition state of the rate-determining step? (A, B, C, D, E) 5. What type of reaction is this energy diagram for? (Endothermic or Exotermic)arrow_forwardWhat is the rate expression for the following reaction ? aA + bB → gG + hHarrow_forward
- I am having trouble solving this problem: The isomerization reaction shown here is temperature dependent. Given the starting material and the Kc, identify the number of molecules of reactant and product observed for each reaction. A=30 Kc: 5 Kc: .5 How would I set this up to solve the problem? I just need some direction I know Kc= B/A but it isn't working outarrow_forwardWhat is the value of the rate law constant for the reaction shown in the picture? a) -1.9 x10^4 b) +1.9 x 10^4 c) -5.2 x 10^-5 d) +5.2 x 10^-5 e) +6.2arrow_forwardIn each of the following three reaction coordinate diagrams, state: (a) Whether the reaction is exothermic or endothermic. (b) Whether the reaction is the slowest, the fastest, or intermediate in rate. (c) If all three reactions have the same entropy change between the reactant and product, which reaction has the largest favorable G0.arrow_forward
- 4.Which of the following factors would not affect rate of reaction? A. Addition of Catalyst B. Climate C. Nature of reactants D. Temperaturearrow_forwardWhich one of the following factors DOES NOT affect the rate of a chemical reaction? concentration C. temperature humidity D. nature of the reactants .The rate of a chemical reaction normally _______________________. increases as temperature decreases decreases when a catalyst is added increases as reactant concentration increases decreases as reactant concentration increasesarrow_forwardDraw the energy diagram of the following reaction (label and draw reactants, intermediates, and products). Label transition state of the rate limiting step and draw the transition state of the rate determining step. Is it a concerted or stepwise reaction? Write the rate law for this reaction. How do we increase the reaction rate? If we use deutrium-tert-butyl bromide such as (CD3)3CBr instead of (CH3)3CBr, will it increase or decrease the reaction rate? Or there is no meaningful rate change. Write reasons for your answer. Draw mechanisms for reactions by drawing arrows and intermediates.arrow_forward
