The equivalent conductivities of acetic acid at 298 K at the concentrations of 0.1 M and 0.001 M are 5.20 and \[49.2\text{ }S\text{ }c{{m}^{2}}\,e{{q}^{-1}}\] respectively. Calculate the degree of dissociation of acetic acid at 0.001 M concentration. Given that: \[{{\wedge }^{\infty }}({{H}^{+}})\] and \[{{\wedge }^{\infty }}(C{{H}_{3}}CO{{O}^{-}})\] are 349.8 and \[40.9\text{ }oh{{m}^{-1}}\text{ }c{{m}^{2}}\text{ }e{{q}^{-1}}\]respectively.

Answer:

12.5
