For the reaction H2 +I2 ⇌ 2HI. Equilibrium concentration of H2, I2 and HI are 8,3 and 24mol/dm3 respectively. Ke of the reaction is:
Correct answer: A. 24
- A. 24
- B. 1
- C. 26
- D. 9
Explanation
Ke=[HI]2 / [H2][I2] - (24) / (8)(3) 24*24 /24 =24

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.
