JEE MAIN - Chemistry (2014 (Offline) - No. 23)
The equivalent conductance of NaCl at concentration C and at infinite dilution are $${\lambda _C}$$ and $${\lambda _\infty }$$, respectively. The correct relationship between $${\lambda _C}$$ and $${\lambda _\infty }$$ is given as:
(where the constant B is positive)
$${\lambda _C} = {\lambda _\infty } + (B)C$$
$${\lambda _C} = {\lambda _\infty } - (B)C$$
$${\lambda _C} = {\lambda _\infty } - (B)\sqrt C$$
$${\lambda _C} = {\lambda _\infty } + (B)\sqrt C$$
स्पष्टीकरण
According to Debye Huckle onsager equation,
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\lambda _C} = {\lambda _\infty } - B\sqrt C $$
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\lambda _C} = {\lambda _\infty } - B\sqrt C $$
