5/6 >> 83% 85 min 06 secs A person is out on the beach for about 1 hour without sunscreen. The amount of UVA radiation hitting a surface at sea level on a slightly clouded day is about 80W/m2. About half of that can be absorbed by the skin. Estimate the number of C-C bonds broken in this person's back (about 0.24 m2) over that period. A typical carbon-carbon bond requires 348 kJ/mol to break. Assume that the average wavelength of UVA is 335 nm. Type your answer here:
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)?
