In case of the decomposition of hydroiodic acid (2HI ⇌ H2 + I2), addition of H2 (at equilibrium condition) will__________________?
Correct answer: C. Diminish the degree of dissociation of HI
- A. Increase the partial pressure of I2
- B. Decrease the partial pressure of HI
- C. Diminish the degree of dissociation of HI
- D. None of these
Explanation
Adding H2, a product, shifts 2HI ⇌ H2 + I2 to the left by Le Chatelier’s principle. This consumes H2 and I2 while forming HI, so the degree of HI dissociation diminishes.
