Question

At some temperature, K = 308 for the gas phase reaction

What is the concentration of HF in an equilibrium mixture established by adding 2.51 mol each of H2 and F2 to a 1.00 L container at this temperature?

[HF] = ? M

What would be the equilibrium concentration of HF if 3.61 mol HF were removed from the above equilibrium mixture?

[HF] = ? M

At some temperature, K = 308 for the gas phase reaction H2 + F2 leftrightarrow 2HF What is the concentration of HF in an equilibrium mixture established by adding 2.51 mol each of H2 and F2 to a 1.00 L container at this temperature? [HF] = ? M What would be the equilibrium concentration of HF if 3.61 mol HF were removed from the above equilibrium mixture? [HF] = ? M
