Following is an equation for iodination of toluene. This reaction does not take place. All that happens under experimental conditions for the formation of radicals is initiation to form iodine radicals, I , followed by termination to reform I2. How do you account for these observations?

A solution of 100 g / L of acrylamide in methanol is polymerized at 25 ° C with 0.1 mol / Lof isobutyryl peroxide whose half-life is 9.0 h at this temperature and the efficiency inmethanol is 0.3. For acrylamide, kp2 / kt = 22 L / mol * s at 25 ° C and the termination is onlyby coupling. (a) What is the rate of polymerization, Rp? (b) How much polymer ishave you prepared in the first 10 minutes of reaction in 1 L of solution?
The reaction of an organic acid with an alcohol, inorganic solvent, to produce an ester and water is commonlydone in the pharmaceutical industry. This reactionis catalyzed by strong acid (usually H2SO4). A simpleexample is the reaction of acetic acid with ethyl alcoholto produce ethyl acetate and water: CH3COOH(solv) + CH3CH2OH(solv) ⇌ CH3COOCH2CH3(solv) + H2O(solv) where “(solv)” indicates that all reactants and products arein solution but not an aqueous solution. The equilibriumconstant for this reaction at 55 °C is 6.68. A pharmaceuticalchemist makes up 15.0 L of a solution that is initially0.275 M in acetic acid and 3.85 M in ethanol. At equilibrium,how many grams of ethyl acetate are formed?

The reaction between peroxodisulphate (VI) ions, S2O82- and iodide ions, I- can be catalyzed by iron(III) ions, Fe3+. Suggest a mechanism for the catalytic reaction.
[Rh(PPh3)3Cl] is a precatalyst that can be activated by dissociation of a phosphine ligand to form an active catalyst, B, which is used in the hydrogenation of alkenes. The active catalyst can then undergo oxidative addition in the presence of H2 to form complex C. Propene coordinates to C to form complex D, which then undergoes a 1,2- insertion step to form E. Reductive elimination of propane from E regenerates the active catalyst B. Draw complexes B – E and hence provide a full catalytic cycle, including the activation step, for the hydrogenation of propene
polystyrene vs polyethylene I need to compare the mechanical and thermal properties of polystyrene obtained by catonic catalysis of styrene, and compare them with polyethylene obtained by metallocene catalysis.
With regards to this, I have been reading journals about activated carbon that is being modified. Now, the activated carbon is modified through acid treatment, and sulfuric acid is added to it. The result was, that there is a presence of SO3-, C=O=C, and C=O on the modified activated carbon. They concluded that the process of sulfonation on the activated carbon treated with sulfuric acid took place. Can you explain the chemistry/mechanism/reaction that happened? Explain in detail and clearly. Thank you so much!
