*Multiple options can be correct
QUESTION: 1

 Which of the following are correct statements           

Solution:

 (A) Δ G = Δ HD - T Δ BS < O as Δ S < 0 so Δ H has to be negative

(B) Micelles formation will take place above T k and above CMC

(C) This solution will be negatively charged.

(D) Fe3+ ions will have greater flocculatibility power so smaller flocculating value.

Solution:
QUESTION: 5

Adsorption is the presence of excess concentration of any particular component at the surface of liquid or solid phase as compared to bulk. This is due to presence of residual forces at the surface  

of body. In the adsorption of hydrogen gas over a sample, of charcoal, 1.12cm3 of H2(g) measured over S.T.P. was found to adsorb per gram of charcoal. Consider only monolayer adsorption. Density of H2 is 0.07gm/cc. In another experiment same 1 gm charcoal adsorbs 100m1 of 0.5M CH3COOH to form monolayer and thereby the polarity of CH3COOH reduces to 0.49.
