For X+Y ⇌ Z Ke= 6 x 10^-7 it means that at equilibrium:
Correct answer: C. X and Y would be favored
- A. Z would be favored
- B. X would be favored
- C. X and Y would be favored
- D. X,Y,Z would be favored.
Explanation
The equilibrium constant (Kc ) is the ratio of products to reactants. A very small K value (much less than 1) indicates that at equilibrium, the concentration of reactants is significantly greater than the concentration of the product. Therefore, the reactants (X and Y) are favored.

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.
