First law of thermodynamics
$Δ U = q + W$
Work of expansion
$W = - P_{e x t} Δ V$
Enthalpy
$H = U + P V$
Enthalpy change
$Δ H = Δ U + Δ n_{g} R T$
Heat at constant volume
$q_{v} = Δ U$
Heat at constant pressure
$q_{p} = Δ H$
Isothermal reversible work
$W = - n R T ln \frac{V _{2}}{V _{1}}$
Adiabatic condition
$q = 0, Δ U = W$
Cp − Cv (ideal gas)
$C_{p} - C_{v} = R$
Enthalpy of reaction (Hess)
$Δ H = \sum Δ H_{p r o d u c t s} - \sum Δ H_{r e a c t an t s}$
Bond enthalpy
$Δ H = \sum (bonds broken) - \sum (bonds formed)$
Entropy change
$Δ S = \frac{q _{r e v}}{T}$
Gibbs free energy
$Δ G = Δ H - T Δ S$
Spontaneity criterion
$Δ G < 0 (spontaneous)$
Free energy and equilibrium
$Δ G^{\circ} = - R T ln K$
Entropy of surroundings
$Δ S_{s u r r} = - \frac{Δ H}{T}$
Second law
$Δ S_{t o t a l} = Δ S_{sy s} + Δ S_{s u r r} > 0$
Heat capacity
$q = n C Δ T$
Enthalpy of neutralization
$Δ H \approx - 57.1 kJ/mol$
strong acid + strong base
Relation ΔG and ΔG°
$Δ G = Δ G^{\circ} + R T ln Q$
Efficiency of a Carnot engine
$η = 1 - \frac{T _{2}}{T _{1}}$
Internal energy (ideal gas)
$Δ U = n C_{v} Δ T$
