Chapter 12, Problem 3ALQ

For the reaction ${\text{H}}_2\left(g\right)+{\text{I}}_2\left(g\right)\rightleftharpoons 2\text{HI}\left(g\right)$, consider two possibilities: (a) you mix 0.5 mole of each reactant. allow the system to come to equilibrium, and then add another mole of H₂ and allow the system to reach equilibrium again. or (b) you mix 1.5 moles of H₂ and 0.5 mole of I₂ and allow the system to reach equilibrium. Will the final equilibrium mixture be different for the two procedures? Explain.
