Question

The molar conductivity of 0.007 M acetic acid is 20 S cm² mol^$-$1. What is the dissociation constant of acetic acid? Choose the correct option.

[$\Lambda _{{H^ + }}^o$ = 350 S cm² mol^$-$1

$\Lambda _{C{H_3}CO{O^ - }}^o$ = 50 S cm² mol^$-$1]

2.50 $\times$ 10^$-$5 mol L^$-$1

1.75 $\times$ 10^$-$4 mol L^$-$1

2.50 $\times$ 10^$-$4 mol L^$-$1

1.75 $\times$ 10^$-$5 mol L^$-$1
