Suppose polyethylene molecules in a solution can exist in either a random-coil conformation or in a fully stretched-out conformation. The stretched-out conformation is 2.4 kJ/mol higher in energy than the random-coil conformation. What percentage of molecules are in the stretched-out conformation at 20 degrees Celsius?
Boltzmann distribution = (Nstr)/(Ntotal) x 100% (Nstr + Nrcoil)
