1.	(i) Write the expression for Freundlich's equation to describe the behaviour of absorption from solution. (ii) What causes charge on sol particles? (iii) Name the promoter used in the Haber's process for the Manufacture of ammonia.
Answer» (i) x/m = kC^1/1n (ii) The charge on the sol particles is due to (a) Electron capture by sol particles during electrodispersion. (b) Preferential adsorption of ions from solution. (c) Formulation of electrical double layer. (iii) Molybdenum acts as a promoter for iron.
