Show what you know about reversible reactions, equilibrium, and shifting equilibria.  We will start our discussion of equilibrium constants today also.


Warm Up 97

(1) Whenever you have a gas reaction, volume changes can result in a shifting of equilibrium.  If the volume of a reaction container is increased, what is the stress and how does the system respond to that stress?

(2) For the following reaction, how will the reaction equilibrium be affected by an increase in temperature?  Identify both the stress and response.

H2O2(l) ⇌ H2(g) + O2(g)    ΔH = +187 kJ/molrxn
