Which of the following value of Ke indicates maximum yield of products?
Correct answer: A. Ke=102
- A. Ke=102
- B. Ke =1
- C. Ke =10-2
- D. Ke = 10-3
Explanation
Ke (equilibrium constant) is the ratio [products]/[reactants]A large value (Ke≫1) means the numerator product concentration is much bigger than the denominator reactant concentration.102=100 means that at equilibrium, the concentration of products is about 100 times greater than reactants, indicating maximum yield of product.

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.
