After allowing the reaction to proceed, you find that the the final concentrations of each reagent $\frac{[\mathrm{C}][\mathrm{D}]}{[\mathrm{A}][\mathrm{B}]}$ once equilibrium is achieved is $\frac{[0.3][0.3]}{[0.7][0.7]}$
What is the value of the equilibrium constant K_eq?

Question

After allowing the reaction to proceed, you find that the the final concentrations of each reagent

\frac{[\mathrm{C}][\mathrm{D}]}{[\mathrm{A}][\mathrm{B}]}

once equilibrium is achieved is

\frac{[0.3][0.3]}{[0.7][0.7]}

What is the value of the equilibrium constant K_eq?
