Equilibrium constant has?
Correct answer: C. Both options A and B are correct
- A. Units
- B. No Units
- C. Both options A and B are correct
- D. A negative value
Explanation
The equilibrium constant formula is kc= concentration of right-hand-side / left-hand-side. If the concentrations are for example mol dm-3/mol dm-3 then the units cancel out and if it is mol2 dm-6 / mol dm-3 then the overall unit will be mol dm-3 as the denominator cancels out.

About Reversible Reactions
A reversible reaction proceeds in both forward and backward directions, so reactants and products continue changing until dynamic equilibrium is established. The topic covers the meaning of equilibrium, the equality of forward and reverse rates, and how concentration, pressure and temperature disturb equilibrium, which is separate from the rate at which equilibrium is reached.
