- For each reaction in question 20, sketch a reaction coordinate energy diagram indicating the starting materials, transition states and any intermediates, if present, in the reaction. Don't worry about the absolute energy of starting materials and products but you can assume that the product is more stable than the starting materials.arrow_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_forwardFill in the missing starting material, reagents, or product for each reactionarrow_forward

Would you predict the ΔHo of Step [1] to be positive or negative? b.How many bonds are broken and formed in Step [2]? Would you predict the ΔHo of Step [2] to be positive or negative? c.Which step is rate-determining? d.Draw the structure for the transition state in both steps of the mechanism. e.If ΔHooverall is negative for this two-step reaction, draw an energy diagram illustrating all of the information in parts (a)–(d).arrow_forwardFor each rate equation, what effect does the indicated concentration change have on the overall rate of the reaction?[1] rate = k[CH3CH2Br][-OH]a. tripling the concentration of CH3CH2Br onlyb. tripling the concentration of -OH onlyc. tripling the concentration of both CH3CH2Br and -OH[2] rate = k[(CH3)3COH]a. doubling the concentration of (CH3)3COHb. increasing the concentration of (CH3)3COH by a factor of 10arrow_forward
- a. Draw an energy diagram for this reaction. be sure to label axes, starting materials, any reactive intermediates and products.b. Draw the transition state of this reaction. If an atom has a positive charge indicate it with sigma+/-.arrow_forwardLabel each statement as true or false. Correct any false statement to make it true. a. Increasing temperature increases reaction rate. b. If a reaction is fast, it has a large rate constant. c. A fast reaction has a large negative ΔG° value. d. When Ea is large, the rate constant k is also large. e. Fast reactions have equilibrium constants > 1. f. Increasing the concentration of a reactant always increases the rate of a reaction.arrow_forwardFill in the missing starting materials, reagents, or major products of each reactionarrow_forward
