The equilibrium constant has no units if the number of moles of products are:
Correct answer: C. Equal to reactants
- A. Less than reactants
- B. More than reactants
- C. Equal to reactants
- D. Half of reactants
Explanation
This is correct. If the number of moles of products and reactants are equal, the units cancel out, resulting in a dimensionless equilibrium constant.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
