Match List-I (Laws) with the List-II (Mathematical expressions):

List-I		List-II
(a)	Henry's law	(i)	$p_{1}=p_{1}^{0} x_{1}$
(b)	Raoult's law	(ii)	$p=K_{H} \chi$
(c)	First law of thermodynamics	(iii)	$\Lambda_{m}=v_{+} \lambda_{+}+v_{-} \lambda_{-}$
(d)	Kohlrausch's law	(iv)	$\Delta U=q+w$

Codes:

a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iv, d-iii

Solution:

Concept:

Match each law with its correct mathematical expression based on standard definitions.

Explanation:

Henry's law states that the partial pressure of a gas is directly proportional to its mole fraction in the solution.

Therefore,

p = K_H \chi

So (a) matches with (ii).

Raoult's law states that the partial vapour pressure of a volatile component equals the product of its mole fraction and the vapour pressure in the pure state.

Therefore,

p_1 = p_1^0 x_1

So (b) matches with (i).

The first law of thermodynamics is based on the conservation of energy.

Its mathematical form is

\Delta U = q + w

So (c) matches with (iv).

Kohlrausch's law states that at infinite dilution, the molar conductivity of an electrolyte is the sum of the contributions of its individual ions.

Therefore,

\Lambda_m = v_{+} \lambda_{+} + v_{-} \lambda_{-}

So (d) matches with (iii).

Answer:

The correct matching is (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii).

Hence, the correct option is Option C.
