Concepts Covered - 1

Smart Tips: Chemical Thermodynamics

Ideal gas

\\ \text {Gas equation: } p V=n R T=N k_{B} T \\ \text { Internal energy. } U=n C_{V} T

\text {Speed of molecule: } v=\sqrt{\frac{3 k T}{m}}

\text {Capacities: } C_{P}=C_{V}+R, \text { Ratio: } \gamma=\frac{C_{P}}{C_{V}}

Molar heat capacities

\text {General: } C_{V}=\frac{1}{2} R \cdot(\# \text { degrees of freedom })

\text { Monoatomic: } C_{V}=\frac{3}{2} R

Thermodynamic process

\text {First law: } \Delta U=Q-W

\text {Work: } W_{A \rightarrow B}=\int_{A}^{B} p d V

\text { Entropy: } \Delta S=\int_{A}^{B} \frac{d Q}{T}

Special processes

Constants

\text {Gas: } R=8.31 \mathrm{J} / \mathrm{K} . \mathrm{mol}

\begin{array}{l}{\text {Boltzmann: } k_{B}=1.38 \times 10^{-23} \mathrm{J} / \mathrm{K}}\end{array}

\begin{array}{l}{\text {Avogadro: } N_{A}=6.02 \times 10^{23} / \mathrm{mol}} \\ {\text {Stefan-Boltzmann: } \sigma=5.67 \times 10^{-8} \mathrm{W} / \mathrm{m}^{2} \cdot \mathrm{K}^{4}}\end{array}
