What is basically Gibb''s free energy change?Ans) The energy associated with a chemical reaction that can be used to do work. The free energy of a system is the sum of its enthalpy (H) plus the product of the temperature (Kelvin) and the entropy (S) of the system... DeltaG=Delta H - T Delta S
Mention one property which is caused due to the presence of F-centre in a solid. a) Write down Nernst equation for single electrode potential.
discuss in detail the basic principle and instrumentation involved in fluorimetry and phosphorimetry
Low grade oxide, sulphide and carbonate ores of copper are treated with dilute sulphuric acid in the existence of oxygen: CuO+ H 2 SO 4 ------------------> CuSO 4 + H 2 O CuC

sir to calculate first order reaction the formula is
what is the name given to the impure copper obtained through this process
Different Atomic Models
Which monomers can undergo free radical, cationic as well as anionic polymerisation with equal ease? CH2=CH2
what is inert paired effect? Explain with examles
Gibb''''s free energy is the useful work done by the system..... G=H-TS.....If G is negative,the rxn is spontaneous & if G is positive , the rxn is non-spontaneous
