2SO2 (g)+ O2 (g),⇌ 2SO3 (g), in the above reaction Kp and Kc are related as
Correct answer: C. Kp=Kcx(RT)-1
- A. Kp=Kcx(RT)
- B. Kp=Kcx(RT)2
- C. Kp=Kcx(RT)-1
- D. Kp=Kcx(RT)-2
Explanation
This matches Δn=−1Correct. It means Kp=Kc/RT.

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.
