Determine the degree of association (polymerization) for the reaction in aqueous solution 6 HCHO ⇌ C 6 H 1 2 O 6 If observed (mean) molar mass of HCHO and C 6 H 12 O 6 is 150:

Options

  1. A0.50
  2. B0.833
  3. C0.90
  4. D0.96

Correct answer

D. 0.96

Step-by-step solution

6 HCHO ⇌ C 6 H 1 2 O 6 Conc. at equilibrium C 1 - α C α 6 α = M T h − M o b s ( n − 1 ) M o b s = 30 − 150 [ 1 6 − 1 ] 150 = 120 5 6 × 150 = 0.96
