Extracted text: Two step growth polymerization reactions are running in the lab. Both have succinic acid and ethylene glycol mixed in equimolar ratios. Reaction one is self- catalysed and reaction 2 has an added catalyst. Depending on the reaction, rate coefficients are 6 x 10-3 mol2.L2.s1 and 0.002419 mol1.L.s1. The initial concentration of ethylene glycol is 1.5 mol.L-1. For reaction two, how many hours would it take to produce a polymer that has an average degree of polymerization equal to 1220.
