    Equivalent conductance of \[1\,M\,\,C{{H}_{3}}COOH\] is  \[10\text{ }oh{{m}^{-1}}\text{ }c{{m}^{2}}\text{ }equi{{v}^{-1}}.\]and that at infinite dilution is \[200\text{ }oh{{m}^{-1}}\text{ }c{{m}^{2}}\text{ }equi{{v}^{-1}}.\]Hence % ionisation of \[C{{H}_{3}}COOH\] is:

    A)  5%        

    B)                    2%

    C)  4%                        

    D)     1%

    Correct Answer: A

    Solution :

     \[\alpha \,=\frac{\Lambda _{\infty }^{C}}{\Lambda _{m}^{\infty }}\]
