Consider the free radical polymerization of vinyl acetate with a thermally initiated kinetic mechanism. If the initial concentration of the vinyl acetate is 0.1 mol/L and the polymerization is carried out at 60°C, with a rate constant of 2.5 x 10^-3 L/(mol·s) for the propagation step and an activation energy of 20 kJ/mol, what is the half-life of the reaction?
