When a peroxide P is heated to 60°C in an inert solvent it decomposes by a first order process and 20% of the peroxide decomposes in 60 min. A bulk monomer is polymerized using this initiator at 60°C, the initial concentration of the letter being 4.0x 10⁻⁴ mol/L. What fractions of the monomer and the initiator should remain unconverted after 10 min ? At 60°C, the system parameters are k/k = 22.34 L mol-'s⁻¹, f = 0.8. [Ans. Monomer 0.67; Initiator 0.963]
