Basics

T = temperature n = moles m = mass P = pressure

V = volume D = density v = velocity M = molar mass

KE = kinetic energy t = time

Boltzmann’s constant, k = 1.38 × 10 -^23 J K-^1

electron charge = - 1.602 × 10 -^19 coulombs

1 electron volt per atom = 96.5 kJ mol-^1

Avogadro’s number = 6.022 × 1023 mol-^1

K = °C + 273 D = m/V

Gases

urms = root mean square speed

r = rate of effusion

STP = 0.000° C and 1.000 atm

PV = nRT

(P + n^2 a/V^2 )(V - nb) = nRT

PA = Ptotal × XA, where XA = moles A/total moles

Ptotal = PA + PB + PC +...

P 1 V 1 /T 1 = P 2 V 2 /T 2

ukrms==3/Tm 3/RT M

KE per molecule = 12 mv^2

KE per mol = 32 RT

rr 12 //= MM 21

1 atm = 760 mm Hg

= 760 torr

Gas constant, R = 8.31 J mol-^1 K-^1

= 0.0821 L atm mol-^1 K-^1

= 8.31 volt coulomb mol-^1 K-^1

(^) = 62.36 L torr mol- (^1) K- 1
Thermodynamics
S° = standard entropy H° = standard enthalpy
G° = standard free energy q = heat
c = specific heat capacity Cp = molar heat capacity at constant pressure
DS° = S S° products - S S° reactants
DH° = S DHf° products - S DHf° reactants
DG° = S DGf° products - S DGf° reactants
