Initiator lj häs hålf the izes 4 times as fast as monomer M2 at 80°C, when initiator I is used for both and all the concentrations are the same. What is the ratio of degree of polymerization for M1 and M2 if they are polymerized with initiator I1 and I2, respectively, the ratio of monomer concentrations being 1:2 and that of initiator concentrations being 1:5? It can be assumed that both polymers terminate exclusively by coupling and that the initiator efficiencies are equal.

For the following two reactions H+Cl2HCl+Cl H+Br2HBr+Br the first reaction has a lower value of A than the second reaction. What can one say about the relative properties of the intermediates HCl2 and HBr2, just from the relative values of A?
List at least four experimentally determined parameters that you, an experimenter, can define when exploring the hydrolysis of ethyl benzoate by aqueous sodium hydroxide.
Pyrolysis involves heating compounds to break them into smaller molecules, and typically involves free-radical chain reactions. Pyrolysis of crude oil fractions is a common method of making smaller hydrocarbons from large-chain hydrocarbons. Pyrolysis of ethane, C2H6, forms ethylene and hydrogen gases C2H4 and H2 as the primary products. Suggest a mechanism for this pyrolysis reaction, labeling your reactions as initiation, propagation, and termination steps.
