Q. The equilibrium cell potential of the galvanic cell
is found to be Ecell,eq = 1.410 V at 298.15K. The standard cell potential is Ecell,eq = 1.360V.
(a) Write the cell reaction and calculate its thermodynamic equilibrium constant at 298.15K.
(b) Use the cell measurement to calculate the mean ionic activity coefficient of aqueous HCl at 298.15K and a molality of 0.500 mol kg-1.
A metal surface is exposed to solar radiations: (1) The emitted electrons have energy less than a maximum value of energy depending upon frequency of incident radiations
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
The correct order of increasing energy of atomic orbitals is: (1) 5p (2) 5p (3) 4f (4) 5p Ans: 5p
Tritium is the isotope of: (1) Hydrogen (2) Oxygen (3) Carbon (4)Sulpher Ans: Hydrogen
compound reacts with oxygen to form 2 oxide x and y. or analysis 1.535g of x yielded 1.365g of copper and 1.545g of y yielded 1.6 a.determine the chemical compound of x and y.b .

Physical properties of Acetone - Aldehydes and Ketones (a) Acetone is a colourless liquid with characteristic pleasant odour. (b) Acetone is inflammable liquid. It boils at
achiral vs diastereomers
can dipole induce dipole forces present between non polar atom?
de-Broglie equation is: (1) n γ= 2d sin θ (2) E= hv (3) E= mc 2 (4) γ= h/ mv Ans: γ= h/ mv
