The instantaneous rate of any reversible reaction is directly proportional to the ratio of conc of products to the reactants raised to their stoichiometric coeff.

For a reactn

aA + bB --> products,

rate = k[A]^a * [B]^b K-- rate constant for rn

for a rn aA + bB <==> cC + dD
Rf=Kf [A]^A * [B]^b
Rb=Kb [C]^c * [D]^d

At eq, Rf = Rb

so..at that point,... Kf/Kb which is Kc..ur eq constant...

If the partial pressure are taken then it is Kp


Dissosciation constant or 'alpha' is the ratio of the molar conductance to the conducatance at infinite dilution...!
