Now you are synthesizing poly(ethylene terephthalate) by step-growth polymerization. How long would it take to reach 99% conversion in an uncatalyzed vs. acid-catalyzed reaction, creating polymer of a number-average molecular weight of 60,000 g/mol? Assume you started with 8 mol/L of monomer, and the uncatalyzed rate constant is 0.012 L$^2$/mol$^2$-min, while the catalyzed rate constant is 1.2 L/mol-min. $\frac{1}{(1-p)} - 1$ $c_0k't = \frac{1}{(1-p)} - 1$ $2c_0^2k_3t = \frac{1}{(1-p)^2} - 1$ Uncatalyzed: 65.1 minutes. Catalyzed: 1030 minutes Uncatalyzed: 6510 minutes. Catalyzed: 10.3 minutes. Catalyzed: 65.1 minutes. Uncatalyzed: 1030 minutes Catalyzed: 6510 minutes. Uncatalyzed: 10.3 minutes.
