AP EAMCET · Chemistry · Chemical Equilibrium
Observe the following equilibrium at \(\mathrm{T}(\mathrm{K})\)
\(\mathrm{H}_2(\mathrm{~g})+\mathrm{I}_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g})\)
Which one of the following does not disturb the above equilibrium?
- A Addition of \(\mathrm{H}_2\) (g)
- B Removal of \(\mathrm{HI}(\mathrm{g})\)
- C Addition of \(\mathrm{I}_2(\mathrm{~g})\)
- D Addition of \(\mathrm{He}(\mathrm{g})\)
Answer & Solution
Correct Answer
(D) Addition of \(\mathrm{He}(\mathrm{g})\)
Step-by-step Solution
Detailed explanation
Addition of \(\mathrm{He}\) gas (inert gas) at constant pressure or volume will not have any effect on the equilibrium of the given reaction as a change of pressure will not affect the number of gaseous moles that are equal on reactant and product side.
