Correct answer
C. a-ii, b-i, c-iv, d–iii
Step-by-step solution
Henry's law relates the partial pressure of a gas to its mole fraction in solution: p = K_H . Thus, (a) matches (ii). Raoult's law states that the partial vapour pressure of a component in a solution is proportional to its mole fraction: p₁ = p₁^0 x₁ . Thus, (b) matches (i). The first law of thermodynamics is the law of conservation of energy, expressed as U = q + w . Thus, (c) matches (iv). Kohlrausch's law of independent migration of ions gives the limiting molar conductivity of an electrolyte as the sum of the l
