aA + bB ⇔ cC + dD
Equilibrium:
(is thermodyn)
  no net change in P or R
  but!!! rxn is still going (rate fwd = rate rxn)
 Keq = [prod]/[react]
 (@ what concent of [R] & [P] the same)
 (apply to eq) *make sure to raise to coeff
 Keq = [C]^{c}[D]^{d}/ [A]^{a}[B]^{b}

Keq = __________
  equilib constant
  constant @ a given temp
  do not include constant solid + liq (b/c can't ∆ concent)
  include (aq) & (g)

Rule of equilib...
Any closed system will proceed towards equilibrium!

Trends in equil...
K_{eq} > 1, @ eq, more prod
K_{eq} < 1, @ eq, more react
K_{eq} = 1, @ eq, equal prod = react

What if not @ eq....
 Rxn Quotient
 Q = [prod]/[react]
Q always moves toward Keq
 Trends
 Q > K_{eq} P → R
 Q < K_{eq} P → R
 Q = K_{eq} @ eq

What if not closed system...
