Catalysts

Front

Topic applied to: Chemical Kinetics What to look for: potential energy vs. reaction pathway, two different lines signify reaction with catalyst and without catalyst. What it means: Uncatalyzed reaction requires more potential energy.

Back

Photoelectron spectroscopy (PES)

Front

Topic applied to: Atomic structure - Quantum What to look for: y-axis is relative number of electrons x-axis is ionization energy OR electron binding energy What it means: The data from the PES provides information about the atomic structure of that particular atom. The peak represents the number of electrons present in the orbital. The peaks that are close together are in the same orbital but with different subshells. The graph follows the electron configuration.

Enthalpy

Front

In each change in state, more heat is released

Back

Deviations from Ideal Behaviour

Front

Topic applied to: Gas Law What to look for: PV/RT vs. P (atm). The purple line (1000K) and the orange line (500K) is the repulsive forces. The green line (200K) is the attractive forces. What it means: n=PV/RT=1

Back

Velocity of a gas

Front

What it applies to: Gases What to look for: number of molecules vs. molecular speed, different curves signify different gases and their distribution of speeds of three different gases at the same temperature What it means: As temperature increases, the velocity increases, and variation of these velocities also increases Urms= ((3RT)/M)^0.5

Back

Second order reaction

Front

Topic applied to: Kinetics What to look for: Y axis is 1/[A] vs X axis time What it means: rate=k[A]^2

Back

Free Energy

Front

Back

Activation energy

Front

Topic applied to: Kinetics Some energy is needed to break the bonds that hold the chemical compounds in the reactants apart. Once the reactant's bonds are broken, they are able to form new bongs with each other and form the products.

Back

Boyle's Law

Front

Topic applied to: Gas laws What to look for: Y axis is V (Volume) vs X axis is P(Pressure) What it means: P1V1=P2V2

Back

Charles' Law

Front

Topic applied to: Gas laws What to look for: Y axis is V (volume) vs X axis is T (time) What it means: V1/T1=V2/T2

Back

Partial Ionic Character of Covalent Bonds

Front

What it applies to: Bonding What to look for: Percent ionic character vs. electronegativity difference What it means: positive correlation between the two terms

Back

Temperature and Rate

Front

What it applies to: Chemical Kinetics What to look for: Temperature vs. rate, as temperature increases, so does the reaction rate What it means: k is temperature dependent

Back

Concentration vs. Time

Front

Topic applied to: Chemical Equilibrium What to look for: Concentration vs. time, lines signify the concentrations of reactants and products over time, and after a certain period of time, the lines will level off What it means: Since at equilibrium, the forward and reverse rates are equal, the products and reactants will be at constant concentration after reaching equilibrium

Back

Dynamic Nature of Equilibrium

Front

Topic applied to: Chemical Equilibrium What to look for: reaction rate vs. time. After a certain period of time, the reactant and product rates are equal What it means: Equilibrium is when the forward and reverse rates are equal

Back

Titration Curve

Front

Topic Applied to: Acids and Bases What to look for: pH vs Volume of Titrant, Buffer Region, Equivalence Point, End Point

Back

First order reaction

Front

Topic applied to: Kinetics What to look for: Y axis is ln[A] vs X axis time What it means: rate=k[A] *also applies to half life reactions if the graph is simply [A] vs. time*

Back

Gay Lussac's law

Front

Topic applied to: Gas laws What to look for: Y axis is P(pressure) vs X axis is T What it means: P1/T1=P2/T2

Back

Zero order reaction

Front

Topic applied to: Kinetics What to look for: Y axis is [A] vs X axis time What it means: rate=k[A]^0=k

Back

Dalton's Law

Front

Topic applied to: What to look for: What it means:

Back

Avogadro's Law

Front

Topic applied to: Gas Law What to look for: the volume vs. moles What it means: V/n=k V: the volume of gas n: the mole number k: the constant (k=RT/P where R=0.0821, T is the temperature in Kelvins, P is pressure) Applied to the gas law: V1/n1=V2/n2

Back

Half Life Graph

Front

Topic applied to: Radioactivity What to look for: Y axis is Amount of substance remaining X axis is time What it means: A= Initial x (0.5)^(time/half-life)
