Acetic acid exists in benzene solution in the dimeric form. In an actual experiment, the van't Hoff factor was found to be 0.52. Then, the degree of dissociation of acetic acid is

Options

A. 0.48
B. 0.88
C. 0.96
D. 0.52.

Answer

C

Explanation

`underset(1-alpha^(|))underset(1)(2CH_(3)COOH) rarr underset(alpha^(|)//2)underset(0)((CH_(3)COOH)_(2)`) `i = 1 - alpha^(|)/2 or alpha^(|) = 2 (1 - i) = 2 (1-0.52) = 0.96`
