A particular reactant molecule "R" is capable of undergoing condensation and forming either a single closed loop (R-> L) or long chain polymer (R+R+R ->P). The rate law for the loop forming reaction is rate(loop) = kLoop[R]; the rate lw for the polymerization reaction is rate(poly) = kpoly[R]^2 a) a beaker with a starting concentration of R equals 0.50M at 60degrees. After 75 minutes of reacting, the concentration of L is 0.10M. Assuming no change in volume or temperature, find k(loop) b. At the 75 minute mark the remaing concentration of R is 0.398M. What can you conclude (qualitatively) about the magnitude of k(poly) relative to k(loop)?

Some reactions proceed through a chain mechanism involving radicals, which are highly reactive species with one or more unpaired electrons. The radicals are produced in initiation steps, through either thermal or photodissociation. Reactions in which the radical centre is transferred are called propagation steps. The radicals are lost in termination steps. Consider the following chain mechanism:(1) AH → A + H·(2) A → B· + C(3) AH + B· → A + D(4) A + B· → P(a) Identify the initiation, propagation, and termination steps.(b) Use the steady-state approximation to deduce that the decompositionof AH is f irst-order in AH.

The first step in the heterogeneoushydrogenation of ethylene is adsorption of theethylene molecule on a metal surface. One proposed explanation for the “sticking” of ethylene to a metalsurface is the interaction of the electrons in the C—C π bond with vacant orbitals on the metal surface. (a) If thisnotion is correct, would ethane be expected to adsorb to a metal surface, and, if so, how strongly would ethane bindcompared to ethylene? (b) Based on its Lewis structure,would you expect ammonia to adsorb to a metal surfaceusing a similar explanation as for ethylene?
