Question

For the reaction $I_2\left(g\right)+H_2\left(g\right)\rightleftharpoons 2HI\left(g\right)$,
what is the effect on the equilibrium position when the pressure of the reaction vessel is increased?

• A. Increased production of products
• B. Increased production of reactants
• C. Fluctuations in the amounts of reactants and products
• D. No impact on the equilibrium
• E. Cannot be determined

Answer 1

The correct option is D No impact on the equilibrium

If there are the same number of moles of gas in reagents and products, changing pressure or volume has no effect on the reaction.
