(a) Derive a relationship between the elevation in boiling point of a solution and the mole fraction of the solute from the thermodynamic consideration.
(b) The molal elevation constant (Kb) and the boiling point for CCl4 are 5.02 deg/moll and 76.80C respectively. Calculate the boiling point of 1.0 molal solution of naphthalene in carbon tetrachloride. 2+3 = 5
Q. Draw a vapour pressure composition diagram for an ideal binary solution obeying this law and compare this with similar diagram showing derivation from Raoult's law. Why do these deviations occur?
Q. Draw a phase diagram for the CO2 system using the following data:
Solid CO2 (dry ice) sublimes at 1 bar pressure and -780C.The triple point is at 5.18bar and 56.60C.The critical point is at 74bar and 31.10C.The density of solid is 1.56 gml-1and that of liquid is 1.11gml-1 .The enthalpy of fusion is 8.34kjmol-1. 5
Q. Calculate the equilibrium constant for the reaction A+2B ---> C , if 1.0 moles of A ,2.0 moles of B and 3.0 moles of C are placed in a 1.0 dm3 vessel and allowed to come to equilibrium. The final concentration of C is 1.4 mol dm-3. 3
Q. Derive an expression for Gibb's Duhem Equation. How chemical potential varies with temperature and pressure?
Borazole is very stable because it is aromatic; each nitrogen contributes two p electrons and each boron contributes zero electrons, for a total of six p electrons in the aromatic
Q. What are the Cationic and neutral ligands? The names of all anionic ligands end in '0' replacing the final 'e' in endings. Sometimes endings are also changed. Thus the given
Explain bond dipole for dimethylmagnesium The bond dipole for dimethylmagnesium should show that C is at the negative end of the C-Mg bond, because carbon is more electronegati
What parts of molecular forces are expected to exist between the species in any three of the following pairs constituting mixtures? (a) He and N2 (b) Cl2 and NO- 3 (c) NH
Number of protons, neutrons and electrons in the element 231/89 y is: (1) 89, 231, 89 (2) 89, 89, 242 (3) 89, 142, 89 (4) 89, 71, 89 Ans: 89, 142, 89
when these are combined...what do they make? And what is it used for?
analysis of group III basic radicals Ti 4+, Th4+, Zr4+, V5+, Ce4+ and UO2 2+
Explain in detail about the Allotropy Allotropy refers only to dissimilar forms of an element within the similar phase or state of matter (i.e. different solid, liquid or gas
Polyethylene: Polyethylene are formed by polymerization of ethylene under high pressure and at moderately high temperature. The resulting polymers are then subjected to substituti
