Question

A solution of aminoheptanoic acid, H2N-(CH2).COOH, in m-cresol at a concentration of 3.3 mol amino acid per kg of solution is polymerized to form polyamide. The reaction is found to be second order in the amino acid concentration with a rate constant of 2.74 x 103 kg/mol rnin. Calculate the time required to form polyamide with a number average molecular weight of 55,000 gr/mol.
