Question

The value of equilibrium constant of a reaction depends upon the initial values of concentration of reactants.
If true enter 1, else enter 0.

Answer 1

The value of equilibrium constant of a reaction is independent of the initial values of concentration of reactants. The equilibrium constant is the ratio between the product of molar concentrations of the products to that of the product of the molar concentrations of the reactants with each concentration term raised to a power equal to stoichiometric coefficient in the balanced chemical equation at equilibrium.

For the general chemical reaction $aA+bB\rightleftharpoons cC+dD$, the equilibrium constant expression is

$K=\frac{K_f}{K_b}=\frac{\left[C{]}^c\right[D{]}^d}{\left[A{]}^a\right[B{]}^b}$

Here, $K_f$ and $K_b$ are the velocity constant of forward and backward reactions respectively. Thus, the value of the equilibrium constant is independent of the initial concentrations.
