Key Equations

P = \frac{F}{A}

p = hρg

PV = nRT

P_Total = P_A + P_B + P_C + … = Ʃ_iP_i

P_A = X_A P_Total

X_{A} = \frac{n_{A}}{n_{T o t a l}}

rate of diffusion = \frac{amount of gas passing through an area}{unit of time}

\frac{rate of effusion of gas A}{rate of effusion of gas B} = \frac{\sqrt{m_{B}}}{\sqrt{m_{A}}} = \frac{\sqrt{ℳ_{B}}}{\sqrt{ℳ_{A}}}

u_{r m s} = \sqrt{\bar{u^{2}}} = \sqrt{\frac{u_{1}^{2} + u_{2}^{2} + u_{3}^{2} + u_{4}^{2} + \dots}{n}}

{KE}_{avg} = \frac{3}{2} R T

u_{rms} = \sqrt{\frac{3 R T}{M}}

Z = \frac{molar volume of gas at same T and P}{molar volume of ideal gas at same T and P} = {(\frac{P \times V_{m}}{R \times T})}_{measured}

(P + \frac{n^{2} a}{V^{2}}) \times (V - n b) = n R T
