This is a constant expression equal to the concentrations of the products, raised to their stoichiometric coefficients, divided by the concentrations of the reactants, raised to their stoichiometric coefficients.
What is the equilibrium constant?
100
This occurs when a substance gains electrons.
What is reduction?
100
This is negative in an exothermic reaction.
What is the change in enthalpy?
200
This type of chemical reaction occurs when iron rusts.
What is oxidation-reduction?
200
These items are related only by a difference of one proton.
What are conjugate acid/base pairs?
200
This happens to the equilibrium constant when a reaction equation is reversed.
What is inversed?
200
This occurs with reduction.
What is oxidation?
200
This is the amount of energy available to do stuff in a chemical system
What is Gibb's free energy?
300
The order of a reaction that has a half-life that does not depend on the concentration of the reactant.
What is zero order?
300
This type of base has a very low percent dissociation.
What is a weak base?
300
This principle describes how reactions at equilibrium will behave if they are disturbed.
What is Le Chatlier's Principle?
300
These are what charges atoms would have, if they had charges.
What are oxidation states?
300
This law determines the floor for entropy values, at absolute zero, or 0 K.
What is the third law of thermodynamics?
400
This is the reason why water does all of the crazy and awesome things it does.
What is hydrogen bonding?
400
This is a method of determining an unknown concentration of a substance using a known concentration of a reacting substance.
What is titration?
400
This applies to reaction with a small equilibrium constant and allows us to not do as much math to calculate equilibrium concentrations.
What is the x is small approximation?
400
In this type of solution, hydrogen ions must be canceled out of a complete and balanced redox reaction.
What is basic?
400
These increase when a system increases in its entropy.
What are microstates?
500
This is the shape of a water molecule.
What is bent?
500
This is equal to the pH only at the most effective point of a buffer solution.
What is the pKa?
500
This tells the current state of reversible reaction at any time.
What is Q?
500
These have to be added to the side with the highest overall charge when balancing an oxidation-reduction reaction.
What are electrons?
500
This is directly proportional to the kinetic energy of a substance.
