1. Given the following equation, predict what will happen in the following scenarios:

2H2S(g) + O2(g) à 2S(s) + 2H2O(g)

1. If O2 is added, what happens to the concentration of [H2O]?

2. If H2S is removed, what happens to the concentration of [O2]?

3. If O2 is added, what happens to the concentration of [H2S]?

4. If S is added, what happens to the concentration of [H2S]?

A system is in equilibrium with the following concentrations:

[PCl3]eq =.200 M

[Cl2]eq =- .125M

[PCl5]eq = .600M

2 What is Kc at this temperature?

b. Enough Cl2(g) is added to increase its concentration by .075 M. Experimental data is taken and shows that the new [PCl5] at equilibrium is .637M. Prove using Le Chatelier's Principle and calculations that the Kc is still the same value as in part a.
