Interpretation:
The number of elementary steps in the mechanism represented by the given free energy diagram is to be determined. The number of locations in the energy diagram that represent intermediates is to be determined. The locations of the overall reactants (R), intermediates (I), transition states (TS), and overall products (P) on the diagram are to be marked.
Concept introduction:
For a mechanism that contains n total elementary steps, there must be n total transition states. Because an intermediate is located in between two transition states, there must be n – 1 locations in the energy diagram that represent intermediates. Transition states are present at energy maxima. Intermediates appear at energy minima.

- Shown is the reaction energy diagram for a reaction with two possible products. Is it possible to use reaction conditions to influence the relative amounts of the two products? O Yes, because the fastest step does not lead to the most stable product. O Yes, because the fastest step leads to the most stable product. Yes, because the mechanism is two steps. O No.arrow_forwardThe free energy diagrams for an E1 reaction mechanism and for an SN1 reaction mechanism are very similar except that there are no differences; they are identical. the intermediate(s) is/are at different energies. the overall products are at different energies. the overall reactants are at a different energies. an SN1 reaction includes two intermediates, while an E1 reaction includes one intermediatearrow_forward17. The rate-determining step for a chemical reaction that proceeds by multiple mechanistic steps, is the step: a) with the highest energy transition state. b) with the largest activation energy. c) with a transition state that looks like the starting material for the mechanistic step. d) with a transition state that looks like the product for the mechanistic step.arrow_forward
- Fill in the blanks: Progress of the reaction This is the reaction diagram of reactant A converted to product D (A → D). The reaction has 2 intermediates. It has 3 transition states. The fastest step in the reaction is the conversion of c to d because it has the lowest activat Is the first step of the reaction (exergonic or endergonic?) because is The overall reaction is (exergonic or endergonic?) because Free energyarrow_forwardConsider the energy diagram in Figure 6. Select the correct statements. * A- This reaction proceeds through a mechanism with three transition states. B- Step 1 determines the rate of the overall reaction. C- The first reactive intermediate is more stable than the second reactive intermediate. D- This reaction proceeds through a mechanism that has three elementary steps. E- The overall reaction is endothermicarrow_forwardClearly label the energy diagram below when answering each part. If there is more than one specific type of label, give an appropriate number afterwards (i.e. Int. 1, Int. 2, etc). State how many step(s) are in the overall reaction, if more than one, clearly label where they start and end Identify the rate determining step (rds) Label all transition state(s) (TS) Label all intermediate(s) (Int.) Label all activation energy(ies) (Ea) Label the heat of the reaction (ΔH) State whether the overall reaction is endothermic or exothermic. please explaing each step. Thank you.arrow_forward
