At 700 K, the equilibrium constant for the reaction H 2 (g) + I 2 (g) ⇌ 2HI(g) is 54.8. If 0.5 mol L-1 of HI(g) is present at equilibrium at 700 K, what are the concentrations of H 2 (g) and I 2 (g) assuming that we initially started with HI(g) and allowed it to reach equilibrium at 700 K?

Options

  1. A0.25 mol L -1 for H 2 and 0.25 mol L -1 for I 2
  2. B0.35 mol L -1 for H 2 and 0.35 mol L -1 for I 2
  3. C0.068 mol L -1 for H 2 and 0.068 mol L -1 for I 2
  4. D0.30 mol L -1 for H 2 and 0.20 mol L -1 for I 2

Correct answer

C. 0.068 mol L -1 for H 2 and 0.068 mol L -1 for I 2

Step-by-step solution

Correct Option is : (C) 0.068 mol L -1 for H 2 and 0.068 mol L -1 for I 2
