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.
What are the Advantages of cold working (i) No heat is required. (ii) Better surface finish is obtained. (iii) Superior dimension control. (iv) Improved strength and h
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.
what do you mean by the terms chromogen,auxochrome,bathochrome and hyposochrome?what role do they play in relation to colour and constitution?
what is molality?
