ICE table
initial, change, equilibrium, when you have initial concentrations and want to find equilibrium concentrations, can use given eq. molarity to find answer or use given Keq
initial concentration
the % concentration of each substrate prior to mixing with the other substrates in solution
equilibrium concentration
The concentration of a substance (usually expressed as molarity) in a system that has reached the equilibrium state.
Kc<<1
reactant favored, you can assume change in reactant concentrations is zero if it is 10^-3 or less
