`K_(1)` and `K_(2)` are the rate constants of forward and backward reactions. The equilibrium constant K of the reaction is -

k_(1) and k_(2) are the velocity constants of forward and backward reactions. The equilibrium constant K of the reaction is

K_f and K_b are the velocity constants of forward and backward reactions. The equilibrium constant K_(eq) of the reversible reaction will be

For a reaction : A rarr B If k_(1) and k_-1 are the rate constants for the forward and the backard reactions respectively then equilibrium constant of the reaction is given as :

The equilibrium constant (K_(P)) of a gaseous reaction is-

In a reaction A+BhArrC+D the rate constant of forward reaction & backward reaction is K_(1) and K_(2) then the equilibrium constant (K) for reaction is expressed as:

In a reaction A+BhArrC+D the rate constant of forward reaction & backward reaction is K_(1) and K_(12) then the equilibrium constant (K) for reaction is expressed as:
