For a gaseous phase reaction, when number of moles of reactants and products are equal:
Correct answer: D. The values of K, and Kc are the same
- A. The values of K, and Kc are different
- B. The value of K, is greater than K.
- C. The value of K, is greater than Kp
- D. The values of K, and Kc are the same
Explanation
For gaseous reactions, K and K are related by𝐾𝑝 = 𝐾𝑐 (𝑅𝑇) Δ𝑛 , whereΔn is the change in moles of gas. If the number of moles of reactants equals products, then Δn=0. Thus, K = K in this case.

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.
