Equilibria
Equilibrium can also exist in between the same species in two different forms e.g. liquid and solid, liquid and gas. An equilibrium constant may also be produced for every of these systems.
Conditions of equilibrium
For the general reaction:
aA+bB→cC+dD
The change in Gibbs free energy, ΔG (see Topic B6) for the reaction at a temperature, T, is given by:
Where Q is the reaction quotient,
The free energy change of both the reverse and the forward reaction is equal. This is when ΔGback=ΔG=0. In this case, the rate constants for the forward and back reactions, kf and kb, and the activities of reactants and products are such that both forward and reverse reactions are occurring at an equal rate and the reaction is at equilibrium.

Can we say that kinetic is part of computational chemistry
Compounds with similar molecular formula but different properties are known as Isomers and the phenomenon is known as Isomerism.
Ratio of radii of second and first Bohr orbits of H atom: (1) 2 (2) 4 (3) 3 (4) 5 Ans: 4
what were the drawbacks of bohr''s atomic theory
Q. Complexation Behaviour of the f-block? Ions of actinide and lanthanide elements have a strong tendency to form complexes with a variety of oxygen and nitrogen donor ligands.
The energy of second Bohr orbit of the hydrogen atom is -328 kJ mol-1, hence the energy of fourth Bohr orbit would be: (1) - 41 kJ mol -1 (2) -1312 kJ mol -1 (3) -164
