Formulas and Key Relations

2. Laws and equilibrium constants

K = [C]^c[D]^d / [A]^a[B]^b

Kp = pC^c · pD^d / (pA^a · pB^b)

Kp = Kc(RT)^Δn

Q = [products]/[reactants] (same powers as balanced equation)

Q = K

3. Henry's law and gas dissolution

m ∝ p

m = kp

Types of Chemical Equilibria

Examples of homogeneous equilibria include H2(g) + I2(g) ⇌ 2HI(g), 2SO2(g) + O2(g) ⇌ 2SO3(g), and CH3COOH(l) + C2H5OH(l) ⇌ CH3COOC2H5(l) + H2O(l).

Kp = Kc(RT)^Δn.
