Question

1. In the reaction A + B → C + D, what will happen to the equilibrium if concentration of A is increased?

2. The equilibrium constant for a reaction is 2 x 10^-23 at 25°C and 2 x 10^-2 at 50°C. Is the reaction endothermic or exothermic?

3. Mention at least three ways by which the concentration of SO₃ can be increased in the following reaction in a state of equilibrium. 

2SO₂(g) + O₂(g) ⇌ 2SO₃(g)

Answer 1

1. The reaction will shift in the forward direction. 

2. Endothermic 

3. following reaction

• increasing concentration of SO₂ 
• increasing pressure. 
• increasing concentration of oxygen.
