What does this General Chemistry II cheat sheet cover?

It has 10 sections: Rates, Integrated Laws, Arrhenius, Equilibrium, Le Chatelier, Acids/Bases, Buffers & Titration, Solubility, Thermo and Electrochem. Together they cover the topics a typical General Chemistry II exam tests, including reaction rates and rate laws, integrated rate laws and half-life, Arrhenius equation and equilibrium constants K.

Is the chemical equilibrium cheat sheet free?

The first part is free to read on this page, with no account needed. The full sheet opens in the app with Unlimited ($4.99 a month or $19 for a semester), where you can edit it, print it or save it as a PDF. It is one US Letter page and prints cleanly in black and white or colour.

Can I bring this General Chemistry II cheat sheet to my exam?

Only if your course allows a note sheet, so check the syllabus. This one is a single US Letter page. If your exam allows a different size, such as a 3x5 or 4x6 index card or one page front and back, Cheat Sheet AI makes one at exactly that size from your own lecture notes.

The sheet was written by our engine from a standard course outline, then a second model fact-checked every formula and statement against it; it corrected 1 statement before publishing. Notation and emphasis vary between courses, so check it against your own lecture notes.

Can I make a General Chemistry II sheet from my own notes?

Yes. Upload your lecture slides, notes or study guide and Cheat Sheet AI writes a sheet in your course's notation, sized to exactly the space your exam allows. Your first sheets are free.

01Rates

Rate: $rate = - Δ [A] /Δ t$ for a reactant, $= Δ [P] /Δ t$ for a product; sign chosen so rate $> 0$ .

Rate law

rate = k [A]^{m} [B]^{n}

$m, n$ = reaction orders; overall order $= m + n$ ; determined experimentally.

Differential form

- \frac{d [ A ]}{d t} = k [A]^{n}

Single-reactant rate law for integrated rate-law work.

Common rate-law facts

Type	Form	Key point
Zero order	rate = k	Linear in $[A]$
First order	rate = k[A]	Linear in $ln [A]$
Second order	rate = k[A]^2	Linear in $1/ [A]$

Method of initial rates

\frac{rate _{2}}{rate _{1}} = (\frac{[ A ] _{2}}{[ A ] _{1}})^{m} (\frac{[ B ] _{2}}{[ B ] _{1}})^{n}

Use trials with one concentration changed at a time.

Catalyst: Lowers activation energy $E_{a}$ ; speeds both forward and reverse reactions; no change to $K$ or $Δ G^{\circ}$ .

Watch out:Do not infer order from balanced equation unless explicitly elementary.

02Arrhenius

Ex.If $k$ doubles when $T$ increases, is $E_{a}$ large or small?

Large $E_{a}$ gives stronger temperature sensitivity; doubling suggests a moderate-to-large barrier.

Watch out:Always use Kelvin; $E_{a}$ in J/mol if using $R = 8.314$ .

03Equilibrium

Equilibrium constant: For $a A + b B ⇌ c C + d D$ , $K = \frac{[ C ] ^{c} [ D ] ^{d}}{[ A ] ^{a} [ B ] ^{b}}$ at equilibrium.

$K_{p}$ vs $K_{c}$

K_{p} = K_{c} (R T)^{Δ n_{g}}

$Δ n_{g} =$ mol gas products $-$ mol gas reactants.

Reaction quotient: $Q$ has same form as $K$ but uses current concentrations/pressures; compare $Q$ to $K$ .

Direction from $Q$ vs $K$

Condition	Shift
$Q < K$	forward, make products
$Q > K$	reverse, make reactants
$Q = K$	at equilibrium

04Acids/Bases

Brønsted acid/base: Acid donates $H X^{+}$ ; base accepts $H X^{+}$ .

Water autoionization

K_{w} = [H X^{+}] [OH X^{-}] = 1.0 \times 1 0^{- 14}

At $2 5^{\circ} C$ .

p-functions

pH = - lo g [H X^{+}], pOH = - lo g [OH X^{-}], pH + pOH = 14

At $2 5^{\circ} C$ .

Acid/base constants

K_{a} = \frac{[ H X ^{+} ] [ A ^{-} ]}{[ H A ]}, K_{b} = \frac{[ BH X ^{+} ] [ OH X ^{-} ]}{[ B ]}

Conjugate pair relation: $K_{a} K_{b} = K_{w}$ .

pKa/pKb

p K_{a} = - lo g K_{a}, p K_{b} = - lo g K_{b}

Smaller $p K_{a}$ = stronger acid.

Strength relations

Species	Stronger means
Acid	larger $K_{a}$ , smaller $p K_{a}$
Base	larger $K_{b}$ , smaller $p K_{b}$
Conjugate base	weaker acid partner = stronger base

Watch out:For weak acids/bases, use equilibrium; do not assume complete dissociation.

05Solubility

Precipitation test

Condition	Result
$Q_{s p} < K_{s p}$	unsaturated, no ppt
$Q_{s p} = K_{s p}$	saturated
$Q_{s p} > K_{s p}$	ppt forms

Common-ion effect: Added ion shifts dissolution left, lowering solubility.

Watch out:Do not forget stoichiometric exponents in $K_{s p}$ and $Q_{s p}$ .

06Thermo

Gibbs energy

Δ G = Δ H - T Δ S

Spontaneous if $Δ G < 0$ ; equilibrium if $Δ G = 0$ .

Standard free energy

Δ G^{\circ} = - R T ln K

Links thermodynamics and equilibrium.

Nonstandard conditions

Δ G = Δ G^{\circ} + R T ln Q

At equilibrium, $Q = K$ and $Δ G = 0$ .

Signs and spontaneity

$Δ H$	$Δ S$	Low $T$	High $T$
+	+	nonspontaneous	spontaneous
+	-	nonspontaneous	nonspontaneous
-	+	spontaneous	spontaneous
-	-	spontaneous	nonspontaneous
