Data Sheet:

Note: Any fact not provided here will NOT be provided during the examination, and it is the student's responsibility to memorize it (if necessary).


R = 8.314 47 J K -1 mol -1 = 8.314 47 × 10 -2 L bar K -1 mol -1 = 8.205 74 × 10 -2 L atm K -1 mol -1 = 6.236 37 × 10 1 L Torr K -1 mol -1.

k = 1.380 65 × 10 -23 J K -1.

g = 9.81 m s -2.

1 J = 1 kg m2 s -2.

1 W = 1 J s-1.

1 N = 1 kg m s -2.

1 Pa = 1 N m -2 = 1 kg m -1 s -2 = 1 J m -3.

1 atm = 101.325 kPa.

1 bar = 1.0 × 105 Pa.

1 Torr = 101325/760 Pa (exactly)


w = -nRT ln(Vf / Vi).

w = -CV ΔT.

ViTi c = VfTf c, c = CV, m/R.

pV&gamma = constant, &gamma = Cp, m / CV, m. For monoatomic perfect gas, CV, m = 3R/2. For non-linear polyatomic perfect gas, CV, m = 3R.

Cp, m = 20.786 J K -1 mol -1 for He, Ne, Ar, Xe.

G(pf) = G(pi) + nRT ln(pf/pi).

G(pf) = G(pi) + Vm(pf - pi).

Gm = Gm* + RT ln(f/p*).

f = φ p.

(p - p*)/p* ≈ VM ΔP/RT

dp/dT = ΔtrsS / ΔtrsV.

p = p* + (ΔfusH/ΔfusV)ln(T/T*).

p ≈ p* + (ΔfusH/ΔfusV)(T - T*).

d ln p/dT = Δ vapH/RT2.

p = p* e , &chi =Δvap(T -1 - T* -1) /R.

dw = γ dσ.

pin = pout + 2γ/r.

h = 2γ/ρgr.

dV = V = (∂V/∂nA) p, t, n' dnA + (∂V/∂nB) p, t, n' dnB

V= nAVA + nBVB, binary mixture.

G = nAμA + nBμB, binary mixture.

nAA + nBB = 0; Σ nJJ = 0.

Δmix G = nRT(xA ln xA + xB ln xB), for perfect gases

Δmix S = -nR(xA ln xA + xB ln xB), for perfect gases

pA = xA pA*.

pB = xB KB.

μA*(g) = μA*(l) + RT xA.

ΔT = KxB, K = RT*2vapH.

ΔT = Kbb, Kb is ebullioscopic constant.

μA*(s) = μA*(l) + RT xA.

ΔT = K'xB, K' = RT*2fusH.

ΔT = Kfb, Kf is cryoscopic constant.

F = C - P +2

p = pA + pB = p*B + (p*A - p*B) xA, in terms of xA.

p = pA*pB / [p*A + (p*B - p*A) yA], in terms of yA.

yA = xAp*A / [p*B + (p*A - p*B) xA].

nα lα = nβ lβ.

k = AeE/RT.

Lindemann-Hinshelwood mechanism: d[P]/dt = kakb[A]2 / (kb + ka'[A]).



Test Grading:

Units are an essential part of the answer, unless a unitless quantity is requested in the problem. Answers without units are WRONG, and will receive zero credit.
