In the process of polyesterification, the average length of a polymer formed by a stepwise process grows linearly with time. The fraction condensed (extent of reaction) and the degree of polymerization at time t = 1.0 hour, of a polymer formed with k r = 1.80 × 10 -2 dm 3 mol -1 s -1 and initial monomer concentration of 3.00 × 10 -2 mol dm -3 , are respectively:
- 10.33 and 2.94
- 20.16 and 1.19
- 30.33 and 1.50
- 40.66 and 2.94✓
Correct answer
0.66 and 2.94
