Reaction coordinate diagrams: Two-step diagram. Label the reactant (R), product (P), intermediate (I"), and transition states (TS; and TS2), plus the axis with appropriate units/labels. 1) Break the diagram up into 2 steps. Which one is the slow step? The fast step? 2) Endothermic or exothermic? Suppose a is added to step one. Sketch the effect of this addition on the diagram. You can identify the intermediates and by remembering: Intermediates are and then Catalysts are added to a reaction (like a reactant), and are at the end. Practice: Identify the reactants, products, intermediate(s), and catalyst(s). Put a star next to the rate-determining step. Step 1 A+B AB (fastest) Step 2 C + AB → ABC Step 3 ABC + D→ ACD + B (fast) diy

The diagram shows the potential energy changes for a reaction pathway. B JA Reaction Pathway Part 1: Describe how you can determine the total change in enthalpy and activation energy from the diagram, and if each is positive or negative. Part 2: Describe how the curve will look if the reaction was exothermic.Be sure to mention changes in the potential energies of the reactants and products and the sign changes of the enthalpy. Potential Energy

Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic. Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.

18) In one of your experiments, you used a Grignard reaction to make a carboxylic acid. „Br 1) Mg 2) CO2 As part of this experiment, the following procedures were given: 1. When the Grignard reaction begins to slow down, place 10 g of crushed dry ice in a 150 mL beaker. Do not take time to weigh the dry ice. Use approximately the amount in the beaker indicated by your instructor. The CO2 is in large excess and will not affect your calculation of percent yield of benzoic acid product. Cover the beaker with a watch glass. 2. When most of the magnesium has reacted and the ether boiling subsides, quickly pour the contents of the tube into the beaker containing dry ice. 3. Add a few milliliters of ether to the test tube and swirl to rinse. Add the rinse liquid to the beaker. 4. Cover the beaker with the watch glass and allow it to stand until the next lab period. During the interim, the excess dry ice will have sublimed. 5. Hydrolyze the Grignard addition product by slowing adding 30 mL of…
