Stresses that change the equilibrium 
(leave space for class notes) 
 
There are 4 parts to answer: stress, how stress affect rxn, make more product or reactant, shift right(more product) or left(more reactant) 
 
1. A change in concentration: 
(What happens to the equilibrium constant: change or unchanged) 
 
 
Stress: _______________________________________________________________ 
 
How stress affect rxn: _________________________________________________ 
 
Circle: Make more product or more reactant 
 
Circle: Favoring: Forward rxn or Backward rxn 
 
Circle: Shift Equilibrium to: Left(more product) or Right (more reactant)

2. A change in temperature(need to know if reaction is exo or endothermic): 
(what happens to the equilibrium constant: change or unchanged) 
 
 
 
 
 
 
3. A change in pressure (for a homogeneous gas system): 
(what happens to the equilibrium constant: change or unchanged) 
 
 
 
 
 
 
4. A change in catalysts: 
(what happens to the equilibrium constant: change or unchanged)
