Which one of the following is correct?

Options

A. The equilibrium constant `(K_(0))` is independent of temperature
B. The value of `K_(0)` is independent of initial concentrations of reactant and products
C. At equilibrium, the rate of the forward reaction is twice the rate of the backward reaction
D. The equilibirum constant `(K_(c ))` for the reaction `Ni (s) + 4CO(g) hArr Ni(CO)_(4) (g)` is `([Ni(CO)_4)])/([CO])`

Explanation

Correct option is (b) as (a), (c ) and (d) are false
(a) `K_(c )` depends on temperature
(c ) At equilibrium both the rates are equal.
(d) `K_(c ) = ([Ni(CO)_(4)])/([CO]^(4))`
