What is not included in the kc expression?
solids and liquids
If K > 1, ___ are favored. If K < 1, _____ are favored
products, reactants
Describe what the following relationships mean: Q > K Q < K Q = L
Q > K = Q is too big; shift left Q < K = Q is too small; shift right Q = K mean that the reaction is at equilibrium
What are the 4 things that equilibrium is disturbed by?
1) adding or removing reactants or products 2) changing temperature 3) changing volume or pressure 4) adding a catalyst
If equilibrium was disrupted by changing volume, the reaction will shift in what type of fashion?
Shifts in whatever direction to reduce number of gas molecules
If equilibrium was disrupted by changing pressure, the reaction will shift in what type of fashion?
Shifts in whatever direction to give more gas molecules
How do you determine if precipitation will occur, given Q?
Q > KSP = precipitation Q < KSP = no precipitation
