Thermodynamics Reference Sheet
Enthalpy
H° = nHproducts – nHreactants
∆H = (energy of bonds broken) – (energy of bonds formed)
∆H = q/mol
q = mCp∆T
(Cp of water = 4

314 J/molK
K = e(-∆G/RT)
G < 0 (spontaneous)
G > 0 (non-spontaneous)
G = 0 (equilibrium)
K > 1 (products favored)
K < 1 (reactants favored)
K = 1 (neither favored
