(a)
Interpretation:
To determine the steps are in the reaction mechanism?
Concept introduction:
An energy diagram is a schematic representation of the energy changes that take place as reactants that are converted into products. An energy diagram indicates how readily a reaction can proceeds, how many steps are involved in the reaction, and how the energies of the reactants, products, and intermediates compare.
(b)
Interpretation:
To label the Ea and ∆Ho for each step, and the ∆Ho overall for the reaction
Concept introduction:
An energy diagram is a schematic representation of the energy changes that take place as reactants that are converted into products. An energy diagram indicates how readily a reaction can proceeds, how many steps are involved in the reaction, and how the energies of the reactants, products, and intermediates compare. The energy difference between the transition state and the starting material is called the energy of activation, symbolized by Ea. The larger the Ea, the greater the amount of energy that is needed to break bonds, and the slower the reaction rate.
The energy difference between the reactants and products is ∆Ho. Because the products are at lower energy than the reactants, this reaction is exothermic and energy is released.
Thus
Ea determines the height of the energy barrier.
∆Ho determines the relative position of the reactants and products
(c)
Interpretation:
To draw the structure of the transition state for each step and indicate its location on the energy diagram

In a multistep mechanism, the step with the highest energy transition state is called the rate-determining step.

Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forward
