Suppose a 3.00 L nickel reaction container filled with 0.0072 M H2 is connected to a 3.00 L container filled with 0.247 M F2. Calculate the molar concentration of H2 at equilibrium. -Hint, find the equilibrium concentration of HF and F2 (as in the above problem), then use the equilibrium expression to find the hydrogen concentration. -When you do the limiting reactant calculation you essentially use up all the limiting reactant. So, hydrogen concentration is approximately zero. But, it can't...
