Which of the following choices is the equilibrium constant of a reaction?

Equilibrium constant Kc is given as [Products]/[Reactants].
It's D.
The following choice is the equilibrium constant of a reaction is Keq = [products]/[reactants]. The correct option is D.
A chemical reaction's equilibrium constant is the value of its reaction quotient at chemical equilibrium.
A state reached by a dynamic chemical system after a period of time has passed in which its composition shows no discernible tendency to change.
Thus, the correct option is D, [tex]\rm K_e_q = \dfrac{[products]}{[Reactants]}[/tex]
