Easy
What does the term 'dynamic equilibrium' mean in a chemical reaction?
Medium
In the Haber process (N₂ + 3H₂ ⇌ 2NH₃), increasing pressure favors the formation of ammonia because:
Medium
Which expression correctly represents the equilibrium constant (Kc) for the reaction: CO + 2H₂ ⇌ CH₃OH?
Easy
If the equilibrium constant Kc for a reaction is very large (>>1), what does it imply?
Medium
In the equilibrium: 2SO₂(g) + O₂(g) ⇌ 2SO₃(g) + heat, what is the effect of increasing temperature?
Hard
Calculate the equilibrium constant Kc for the reaction: H₂ + I₂ ⇌ 2HI, if at equilibrium [HI] = 0.4 M, [H₂] = 0.1 M, and [I₂] = 0.1 M.
Hard
In the industrial Contact process for sulfuric acid, why is the temperature maintained around 450°C despite the reaction being exothermic?
Easy
Which of the following changes will NOT affect the position of equilibrium for a reaction in solution?
Medium
For the reaction: N₂O₄(g) ⇌ 2NO₂(g), the equilibrium constant Kc = [NO₂]² / [N₂O₄]. If initially only N₂O₄ is present, which statement is correct as equilibrium is established?
Medium
In an equilibrium reaction, the value of Kc is 1 × 10⁻⁵. What can be inferred about the reaction?
