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 po
garik1379 [7]

Explanation:

The given data is as follows.

       Concentration = 3.3 mol

      Rate constant = 2.74 \times 10^{3} kg/mol min

      Molecular weight = 55000 g/mol

      \tau = C_{A_{0}} \times \int_{0}^{X_{A}} \frac{dX_{A}}{-r_{A}}

Initial concentration (C_{A_{0}}) of aminoheptanoic is 3.3 kg/mol.

       -r_{A} = 2.74 \times 10^{3} kg/mol min

Hence, putting the given values into the above formula as follows.

    \tau = C_{A_{0}}\times \int_{0}^{X_{A}} \frac{dX_{A}}{-r_{A}}

              = \frac{3.3}{2.74 \times 10^{3} kg/mol min} [X_{A}]^{0.1}_{0}

              = 120.43 min

Thus, we can conclude that total time required to to form polyamide is 120.43 min.

Sunny_sXe [5.5K]

Answer: option D) hypothesis

Explanation:

Kim proposal is an hypothesis, because it is an assumption that will ONLY be accepted as true (i.e becomes a theory) when butadiene successfully makes the glue stickier in several conducted experiments.

But, at the moment Kim proposal is an hypothesis.
