Question

In the reaction, H2(g) + Br2(g) ⇌ 2HBr(g), what will happen if there is a change in pressure?

• A. equilibrium moves left
• B. equilibrium moves right
• C. there is no change in equilibrium
• D. we cannot say

Answer 1

Answer:

C. there is no change in equilibrium

According to Le chatelier’s principle, there will be no effect of pressure on equilibrium if the chemical equation has the same number of moles of reactants and products hear the moles on the left side is equal to the moles on the right side that is 2.
