State whether reactants or products will be favored by an increase in the total pressure (resulting from compression). If there is no change, explain why that is so.

Cl2(g) <-> 2Cl(g)

Thanks!

To my understanding, when pressure increases then equilibrium shifts to the side with the least moles of gas. So, one mole of Cl2 versus two moles of Cl. Cl2 would be favored, I believe.

Dr. Lavelle mentioned in lecture a quick way to do this problem. Since pressure is increasing and volume is decreasing. When that happens, you know that if there are more moles on the left, the reaction shifts right. If there are more moles on the right, the reaction shifts left. In this case there are 2 moles of Cl on the right and only 1 mole of Cl2 on the left. Thus the creation shifts to the left, toward the reactants. Hope this helps.
