Equilibrium Constant:
Kc= [product]/[reaction] = [C]c [D]d / [A]a [B]b
Rate of Reaction= Change in concentration of reactant or product/change in time
H2 + I2 2HI Exothermic- heat on product side
Endothermic- heat on reactant side
Heat + shift to products
Endo Heat - shift to reactants
Heat + shift to reactants
Exo Heat - shift to products
Acids- produce H3O+ in water
Are electrolytes
Sour
Litmus paper turns red
Neutralize
Bases- produce OH- in water
Are electrolytes
Bitter/ chalky/ soapy/ slippery
Neutralize acids

Ka = Acid Dissociation Constant
Ka = [C] [D]/ [A] [B] omits pure liquids
Bronsted- Lowry:
Acids provide a proton
Bases accept a proton
Kw= Water Dissociation Constant
Kw = [H3O+] [OH-]
Kw @ 25 = 1.0 x 10-14
H3O+ > acidic
OH- > basic
