Chemistry Past Questions and Answers

A catalyst does not change the equilibrium position because it:

In the reaction:<br/>PCl₅(g) ⇌ PCl₃(g) + Cl₂(g)<br/>what will happen if the container volume is reduced:

In the equilibrium:<br/>CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)<br/>adding steam will:

In the Haber process:<br/>N₂(g) + 3H₂(g) ⇌ 2NH₃(g)<br/>the use of moderate temperature is preferred because:

In the equilibrium:<br/>2SO₂(g) + O₂(g) ⇌ 2SO₃(g)<br/>which condition would give the highest yield of sulfur trioxide:
