Chapter 2 Notes
Reversible Systems
Reactions can move left and right
Equilibrium symbol ⇌
Irreversible equations only one way
Closed system has no matter transfered
Rate of forward reaction = rate of backward reaction
Equilibrium
Can be changed by pressure dilution or temperature
Concentration
Reactants
Pressure up
Favours forward
Pressure Down
favours backward :
Products

Le chatelier's principle
system will oppose changes and from new equilibirum
Acid base dissociation
Ka = acid dissociation constant
Kb = base dissociation constant
Kw = water
Kw = 1.00 x 10^-14
Ph = -log10[H+]
pOH = -log10[OH+]
Equilibrium constant
Kc=[P]/[R]
Kc > 1
More reactants than products
Kc < 1
More products than reactants
ICE
I = inital concentration
C = change
e = equilibrium
