For the Reaction System, H₂(g)+ X₂(g) 2HX(g), K_c =

For the reaction system, H₂(g) + X₂(g) 2HX(g) , K_c = 24.4 at 300 K. A system made up from these components which is at equilibrium contains 0.150 moles of H₂ and 0.600 moles of HX in a 3.00-liter container. Calculate the number of moles of X₂(g) present at equilibrium. Hint: Be sure to find molarities of all reactants and products before finding the equilibrium amount of X₂.

A) 0.0984 mol
B) 0.164 mol
C) 0.0328 mol
D) 0.131 mol
E) 0.393 mol
