Question

1. Soda water is prepared by dissolving CO₂ in water under high pressure. What is the principle involved in this process? 

2. At 1000 K, equilibrium constant K_c for the reaction 

2SO₃(g) ⇌ 2SO₂(g) + O₂ (g) is 0.027. 

What is the value of K_p at this temperature?

Answer 1

1. Henry’s law 

2. K_p =K_c (RT)^∆n 

∆n = 3.2 = 1

K_p = 0.027 × (0.0831 × 1000)¹ = 2.2437
