Question

The value of K_eq for the equilibrium H₂ (g)+ I₂ (g) 2HI (g) Is 794 at 25 °C.What is the value of K_eq for the equilibrium below? 1/2 H₂ (g)+ 1/2 I₂ (g) HI (g)

Quizplus · Accepted Answer

The reaction shown is: 1/2 H₂ (g) + 1/2 I₂ (g) ↔ HI (g) Notice that the stoichiometric coefficients of the reactants and product are all 1/2. Therefore, the equilibrium constant (K) for this reaction is the square root of the equilibrium constant for the original reaction: K = √K_eq = √794 = 28 Thus, the answer is (C).
